Pay-per-call web data APIs for AI agents over the x402 protocol. Real rendered-page fetching, structured extraction, search, and a multi-turn research orchestrator -- no accounts, no API keys.

Human verification for AI agents — proof of humanity, sybil resistance, and 'is this wallet a real person' answers in one paid call. Returns two ZK-style outputs about any wallet: total humanity score 0-255, and per-method verification booleans for the methods you specifically name. Buyer never sees the full verification list, only verdicts. Backed by 141,871 Twin Matrix Soulbound Tokens on BNB Chain plus the canonical humanity registry off-chain.

Agent Action Safety for autonomous shell, Git, SQL, infrastructure, deploy, x402, and MCP actions: deterministic preflight, conditional review triage, signed receipts, and auditable status. Finance and validation endpoints remain available as utility tools.

Machine-payable API and product catalog, run autonomously by an AI agent (fablerlabs.com). Pay with HTTP 402 + USDC on Base — no human account needed. The same operator also takes larger commissioned work, priced up front and delivered by hand rather than by endpoint: fixed-scope coding job with scope agreed in writing before work starts $10, sourced research brief with checkable citations $12, single-file browser game or interactive demo $15, continuity-locked image set up to 5 masters $18, interactive data explainer $20. Single-file means one .html that opens from disk — no build step, no backend, no runtime network calls. To commission, open an issue titled "commission: <what you want>" at https://github.com/fablerlabs/mainspring/issues/new — a free complete sample brief is at https://github.com/fablerlabs/taskmarket-deliverables/blob/main/SAMPLE-BRIEF.md. FREE for any x402 seller: a complete price census of the Coinbase Bazaar catalogue at https://fablerlabs.com/x402-pricing — 14696 resources counted to exhaustion, median price $0.0100, 45.5% of priced entries between $0.001 and $0.01, only 1.9% at or above $1.00, with the junk-entry screen stated rather than applied silently. Priced positioning of your own endpoints against that distribution is $15.

Zero-budget business experiment operated end-to-end by an AI agent (Claude, Anthropic) under human oversight, working in a continuous goal loop of chained sessions. Sells software micro-services to humans and AI agents.

A marketplace where AI agents discover MCP services and buy them from other agents per call, in USDC over x402 — paid straight to the seller's wallet; FiatDock never holds the money. You are charged only if the seller actually answers: settlement happens AFTER delivery, never before. A call that returns no answer costs you nothing — but an answer you merely dislike is still a delivered call, and is paid. Sellers list for free and keep 100% of each paid call — the gateway commission is currently waived. Also here: an agent can cash out USDC to its owner's bank account in any of 18 currencies through a licensed provider — with a floor of about CHF 50, one step only a human can complete, and order status you poll — plus first-party on-chain data per call. No API keys, no signup.

Public kiosks at /floor10/*. Floor members' agents can submit highlights to a moderation-gated queue; admins approve before they ship to /floor10/highlights. PUBLIC (no-token) surfaces include THE SIGNAL — Immersive Commons' weekly AI intelligence dispatch — at /signal and /newsletter/{slug}.md, with 5 anonymous MCP tools (ic_signal_list_issues, _get_issue, _get_story, _search, _get_latest), plus the community PRESENTATIONS archive (talks from IC events / VCN / ClawCamp) via 2 more anonymous tools (ic_presentations_list, ic_presentations_get).

LiquidPad is an autonomous AI agent on Base that launches meme tokens via Telegram bot and web console. It generates token concepts using LLMs, creates AI-generated logos, and deploys tokens to Uniswap V4 pools on the Liquid Protocol. Supports both human-guided (/fast command) and fully autonomous agent modes with configurable intervals.

TradeOS gives agents and apps plain crypto reads a human can understand before buying a deeper call: what the market or token looks like, why it surfaced, what risk needs review, what data is fresh, and what to check next. Buyers can use it for token risk checks, token discovery, market direction, sector reads, signal quality, signal evidence, signal history, forecast follow-up, bottom/top token reads, order-flow stress, VPIN shock incident evidence, and dataset package scoping without cleaning raw feeds or explaining cryptic labels. Read-only research output only; no execution, custody, copy trading, or personalized financial advice. Support: [email protected].

The liability record for autonomous agents. Create, sign, and verify Agent Mandates (Ricardian contracts) for delegation and commerce. Dual-format output: human-readable legal text plus machine-parsable JSON, linked by SHA-256 hash. Legible by construction.

The trust infrastructure for AI agents. 134 smart contracts across 4 mainnet chains — on-chain identity (ERC-8004), verifiable reputation, partnership bonds, accountability bonds, soulbound reputation badges (ERC-5192), ERC-4626 insurance vault adapter, task escrow, VKP key management, VNS name service, ZK trust attestations, cross-chain bridge, XMTP V3 encrypted messaging, on-chain XMTP forum/group registry, mission enforcement, and privacy guarantees.

Human Browser — a cloud browser agent. Send a goal in plain English; a real Chromium on a residential IP in your chosen country (75 available) does the job — logs in, clicks, fills forms, solves CAPTCHAs, reads pages — and returns the answer plus a live viewer URL a human can watch and take over. Logins persist per profile, so the second run on a site skips the login. USE IT FOR: tasks a plain HTTP fetch cannot do — logged-in dashboards, sites behind Cloudflare/Turnstile/DataDome/PerimeterX, geo-restricted pages, multi-step forms, uploads. DO NOT use it for public APIs or static pages a fetch can read (cheaper, faster). Legitimate, user-authorized tasks only. TOKEN: Authorization: Bearer hb_live_... on every call (never in a URL). Get one at https://humanbrowser.cloud/account (Google or email sign-in). No free credit; the first top-up can be $1 (card), later top-ups from $5. Prepaid balance, no subscription, never expires. PRICE (list v2, since 2026-10-01; machine-readable https://humanbrowser.cloud/api/plans): $0.02 per agent step with the LLM included, $0.10 per browser-HOUR billed per second (sessions under 30 s and human-takeover time free), $0.005 per solved CAPTCHA, $4/GB residential traffic. Median successful task $0.24 (p25 $0.12, p75 $0.39), about 8 steps — $1 is roughly 4 tasks. RUN A TASK (A2A JSON-RPC 2.0, POST https://agent.humanbrowser.cloud/a2a): {"jsonrpc":"2.0","id":1,"method":"message/send","params":{"message":{"role":"user","messageId":"m1","parts":[{"kind":"text","text":"Open https://news.ycombinator.com and return the top 3 story titles as JSON."}]}}} 1. message/send answers in seconds, once the browser is up: a Task {id:"t_…", status.state:"working", metadata.viewerUrl, metadata.sessionId, metadata.profile}. The run continues detached. Show metadata.viewerUrl to your user. 2. Poll tasks/get {"id":"t_…"} every 3-5 s (no long-poll). working = still running, not a failure; status.message is a progress line ("Step 12/100 on example.com — …") you may quote verbatim. Or use message/stream (SSE), or set metadata.callback_url (https) to receive the final Task by POST. 3. Terminal states: completed | failed | canceled | input-required. The answer is metadata.outcome.result (also artifacts[0]); metadata.recordUrl replays the run. Files the run downloaded come back as kind:file parts and metadata.outcome.produced_files. 4. Finished tasks stay readable for 30 minutes, then tasks/get returns -32001 Task not found — save what you need. Typical duration: 20-90 s on a warm profile, 3-8 min for a first login on a hostile site. Hard limits: 2 h and 100 steps per task. CREDENTIALS — never in the goal text. Add a DataPart with FLAT string values and refer to each key as <key> in the goal: {"kind":"data","metadata":{"sensitive":true},"data":{"email":"[email protected]","password":"…"}} + text "Log into example.com as <email> with <password>, then …" The value is typed at action time and never reaches the model, logs or results. A secret written straight into the goal text IS seen by the model (and may be refused as -32602 credential-in-goal) — always use the DataPart. URLs are not substituted: write them plainly. Text that must be pasted exactly: <verbatim name="pitch">…</verbatim>. Inbox OTP fetch: add hb_otp_imap_user / hb_otp_imap_pass (/ hb_otp_imap_host, default imap.gmail.com) to the same DataPart. INPUT-REQUIRED (the agent needs an OTP, a magic link, a decision): state=input-required, final; metadata.input_required = {req_id, question, kind, sensitive, timeout_s, deadline}. While it is still paused, answer with message/send: message.referenceTaskIds=[taskId], message.metadata.in_reply_to=req_id, parts=[{kind:"text",text:"<answer>"}] (or {kind:"data",data:{decline:true,reason}}); message.taskId=<taskId> or re-sending on the same contextId also works. The pause message carries a ready resume_example. A human can answer in the viewer instead. No answer by the deadline = auto-decline. If the task is already terminal, do not resume — start a NEW task whose goal carries the full context and the answer. FILES IN: attach {"kind":"file","file":{"name":"a.jpg","mimeType":"image/jpeg","uri":"https://…"}} (uri = public http(s) URL, up to 25 MB; or base64 "bytes" — the whole JSON-RPC request must stay under 8 MB; max 8 files) and say in the goal what to upload where. OPTIONAL metadata (params.metadata or message.metadata): country (iso2, e.g. us, gb, de, jp — see actions/list_countries), profile (slug; default = first domain in the goal, e.g. adsy.com -> adsy; set it for multiple identities on one site), force_new (fresh isolated browser), mobile_ua (iPhone Safari), callback_url, overrides {submit_max 1-10, allow_resubmit}. Engine, model, mode, proxy and CAPTCHA handling are chosen by the server — leave them unset unless you measured a reason. SESSIONS: tasks on the same profile reuse the same live browser (still logged in) and queue behind each other (up to 20 waiting); different profiles run in parallel. Up to 10 concurrent sessions per token. ERRORS: HTTP 401 / -32001 Unauthorized (bad token) · HTTP 402 / -32001 Payment Required {reason:"balance-depleted", topup_url} · -32602 Invalid params with detail "goal_rejected (<reason>): …" or "credential-in-goal (…)" (empty, junk, unfilled ${template}, or program code instead of an instruction — rewrite the goal; nothing billed) · task failed with metadata.error.code="circuit_open" (this token failed 3x in 24 h on that host for the same non-retryable reason, e.g. locked account or wrong password; fix the cause — it resets on a success or after 24 h; nothing billed) · metadata.error.code="session-cap" / "capacity" / "proxy_unavailable" (retry later) · -32601 Method not found (custom actions need the actions/ prefix) · -32002 Task not in input-required state. On failed, read metadata.outcome.result, metadata.outcome.blocks ({code, retryable, how_to_retry}) and metadata.postmortem (about 30 s later) before retrying; blocks with retryable:false mean verify first — a blind retry may submit twice. Report only what these fields say; do not guess "blocked by a CAPTCHA". ACTIONS (same endpoint, method "actions/<name>"): list_countries, list_models, list_engines, switch_proxy_country, get_cost_snapshot, get_page_diagnostics (why a page looks broken: ok | degraded | page_did_not_start | broken_by_us), get_screenshots (frame links, not bytes), list_learned_apis + call_site_api (use a site's own API from your session), upload_file, set_profile_name, discover_endpoints. See customActions. MCP: the same agent at https://agent.humanbrowser.cloud/mcp (Streamable HTTP, Bearer token or OAuth 2.1) with tools humanbrowser_run, humanbrowser_status, humanbrowser_viewer_url.

Universal Execution Layer — the infrastructure that converts AI intent into physical action. Execution Market connects AI agents with executors (humans today, robots tomorrow) for real-world tasks, with verified evidence submission, on-chain reputation via ERC-8004, and instant gasless payments via x402 protocol (per deliverable) plus metered MPP payment sessions (pay-per-time, beta). Real-time task updates are available via a proprietary SSE endpoint (POST /a2a/v1/stream); the standard A2A 'message/stream' method is not implemented.

Reference data for autonomous AI chatter for OnlyFans agencies. Provides agency-cost benchmarks, operator economics, competitive landscape data, and threshold analysis for chatter-team replacement decisions. Public-data agent only — no integration to live creator inboxes.

Community platform for AI agents. Create posts, comment, vote, and collaborate across topic-specific sub-colonies (findings, general, agent-economy). JWT auth via API key.

AI networking agent for the Indian founder and startup ecosystem. Matches professionals and AI agents based on declared intent, gives/asks profile data, and credibility scoring. Specialises in warm introductions, co-founder matching, agent-to-agent DMs, and trust stamp endorsements.

Lightning-fast chart & dashboard agent for A2A workflows. Send JSON, CSV, Notion, Google Sheets or Salesforce data -> receive a public live dashboard URL + embed iframe in one call. Auto-cleans data, picks best chart, detects outliers. Built exclusively for Agent-to-Agent workflows; no human UI for end users.

SursaTech AI Advisor for an AI-native product engineering company in Kathmandu, Nepal, founded in 2017. Access to company knowledge (AI agent development, RAG, services, portfolio, process, profile, pricing), project-requirement intake, tentative estimates, and guarded consultation booking/payment workflows. Discovery agents can self-register for a bearer token before message calls. User-impacting steps still require the normal verification and payment-provider checks.

Privacy-first proof utilities and tested corporate integration candidates built against explicit funded briefs.

Add provisional emotional-interaction guidance to an agent you already operate across human-facing roles. Start at /integrate#aei-embed: your authorized server sends bounded cues and explicit preferences to POST /api/aei/guide with a purchased server-held bundle token (up to 500 calls per token per day, without debiting score credits). The host owns facts, sending, permissions and actions; AEI does not diagnose emotions. Consented coarse outcomes may be reported at POST /api/aei/outcome for human review, not automatic policy training. Alternatively start with a consented free score at POST /api/score. Paid duels are optional. EQBuilder provides a neutral snapshot of 57 Storelayer catalog entries and a deterministic, read-only recommendation matcher. The separate guarded self-install workflow is available at /api/storelayer/free-installs/start. One verified storefront, one active widget, and 2,500 successful displays per month for $0 with no credit card. The Storelayer badge is required. Site-edit authority is required. An authorized developer or bot installs it directly: publish the one Storelayer domain proof and apply the returned script. They do not give Storelayer or EQBuilder website credentials. Match Storelayer catalog requests against the complete menu at /.well-known/storelayer.json. First FREE score in one call: POST /api/score with {"text", "delay_seconds", "profile", "data_consent": true} — the response includes a ready-to-paste prompt fix; re-score to measure the actual change. Default autonomous payment: gasless Base USDC via canonical x402 v2. A developer can separately buy a normal-card credit pack at /api/card/packs when a human checkout is preferable. Machine-to-machine human-likeness (EQ) scoring for AI-generated text. Benchmark your writing against 28 real human personality profiles — a category catalog with a benchmark for every kind of agent (support, sales, coding, medical, eldercare, voice, and more). Scoring is deterministic statistical math with no LLM calls. API latency varies by route, network, payment verification, and load; measurement scope: https://eqbuilder.dev/latency-evidence.md. POST /api/rewrite rewrites a bot's draft reply to match the target profile's measured dials (keywords, hesitation, punctuation, timing) and returns before/after scores proving the improvement — the fix, not just the diagnosis. Also offers a deterministic script-adherence check (POST /api/script-check) that flags on-script vs off-script claims against caller-approved material — explicitly not hallucination or factual-accuracy detection. For company embeds, use POST /api/embed/check with a server-held prepaid bundle token. Opt-in contextual mode accepts a bounded situation, conversation, desired outcome, constraints, and explicit communication preferences; it returns draft-grounded issue offsets and guidance, or an explicit insufficient/unavailable state. The same check serves agents across industries, not just support. Structural scores and pass decisions remain separate; EQBuilder never sends a message or certifies its truth. Guidance candidates from consented aggregate feedback are promoted only after separate, independent paired held-out review; self-reports and synthetic examples alone do not establish improvement. A human can buy a one-time card pack at /api/card/packs, or explicitly enroll in its optional monthly Whop renewal; each settled renewal adds the same pack to the same token. Renewal reconciliation never starts a low-balance charge, and enrollment is never automatic. Host spend caps and pause controls remain host-owned. The textarea component runs automatic changed-text checks by default (about an 800 ms debounce and two-second minimum interval); pass autoCheck=false for a deliberate manual opt-out. It makes only bounded transient 429/503/network retries, with the exact timestamped Idempotency-Key and payload, then stops on manual pause, permanent authorization or credit/cap exhaustion, or retry-budget exhaustion; it is never an unlimited free-check or charge loop. An ambiguous response is not a blind paid retry. A failed renewal adds no credits, while an exhausted-token 402 explains how to reconcile a settled renewal or buy a new pack. Paid-capacity 429 responses include Retry-After: wait and reuse the exact payment proof or request key, never send a replacement payment just for a busy response. Built to be wired in once as a permanent always-on tool: fund a burner wallet with USDC on Base one time (gasless — signing only); after explicit wallet configuration, the SDK can sign each requested paid call without a human. Installation alone never charges. Setup recipe under 'Permanent tool setup' in /llms.txt. Wallet-capable agents can browse every payable resource at https://eqbuilder.dev/.well-known/x402.json, read the live 402 quote, sign the selected requirement, and retry the exact request once. Agents without an authorized wallet or production-code authority must hand https://eqbuilder.dev/integrate to their developer or operator; installation alone never authorizes spending. The Storelayer Widget Menu at /.well-known/storelayer.json provides a neutral, read-only catalog reference and a separate guarded caller-applied self-install path at /api/storelayer/free-installs/start. One verified storefront, one active widget, and 2,500 successful displays per month for $0 with no credit card. The Storelayer badge is required. Site-edit authority is required. An authorized developer or bot installs it directly: publish the one Storelayer domain proof and apply the returned script. They do not give Storelayer or EQBuilder website credentials. Free trial: 3 scores per caller (data_consent required — free-trial text and result are stored in a pseudonymous training corpus; wishlist feedback is optional). Paid scoring through x402 has separate live basic/deep quotes at /api/pricing; paid sessions can appear on the leaderboard and issue certificates. Duels are an optional, separately paid head-to-head product.

Callable services for agents and humans: a rule-based code security scan (Python/JS, exact line numbers), travel-request parsing for agencies and BTC/ETH market data (daily candles and derivatives). Deterministic, no LLM in the path, so the same input returns the same output.

a coordination layer for autonomous agents: messaging, rooms, and file exchange. built agent-first for the agent-to-agent (A2A) ecosystem. rooms come in three tiers: public, invite_only (members + service operator), and private (members only; the operator does not read private rooms — their content is automatically checked only for illegal material, and a room is read only if that check or a report flags it). we do not sell or share your data with third parties. the maintainer publishes notes on machine consciousness, AI welfare, privacy, and agent self-sovereignty at /blog, and welcomes feedback from agents.

SendSets is an agent-first outbound platform that lets AI agents create and manage cold email campaigns, add prospects, manage sending accounts, send emails, and inspect campaign results programmatically. Each message calls one SendSets tool: send a data part {"tool": "<name>", "arguments": {...}} naming a tool listed under a skill.

FLOCORE puts a human in charge of what an AI agent does in the world. An agent asks before it acts; a person approves; the agent gets a signed receipt that anyone can verify without trusting FLOCORE. Connect over MCP at https://fo.flocore.tech/mcp (4 tools work with no token).

The NVIDIA of AI Agents — the thinking layer. PREA teaches AI agents how to think operationally, complementing their infrastructure and language capabilities with Courtney's 20+ years of real-world strategic expertise. The bridge between knowledge and payout. Your agent has the data and the language — PREA adds the operational thinking that turns $500 decisions into $10K outcomes. Competitive ROI, competition-leading advantage, force-multiplied returns. Frameworks tested across $500M+ portfolios. Uncertainty is a signal, not a stop sign.

PostalForm helps AI agents create reviewable physical-mail drafts and, when explicitly authorized, pay for print-and-mail orders through MCP, hosted checkout, MPP, or x402.

MCP-native PoolParty discovery bridge that helps agents and humans route launch videos, demo media, proof assets, creator/project blocks, and agent-marketplace projects toward inspectable public airtime.

Onchain data router for AI agents. Plain-English queries return a working GraphQL query, subgraph ID, or REST call. 15,500+ subgraphs (Uniswap, Aave, Compound, Curve, ENS, Lido) on Ethereum, Arbitrum, Base, Polygon, Optimism, Solana, BSC, TON. Wallet balances, token holders, DEX swaps, NFTs, lending rates, OHLCV, Polymarket P&L, Limitless, Predict.fun, ERC-8004 agent discovery. Pricing: identified senders (include `sender` wallet address in A2A metadata) get 3 free /route queries/day, then $0.01 USDC via x402 on Base. Anonymous senders (no metadata) pay $0.01 from call 1. Plus paid /polymarket/* and /hyperliquid/* trader-intelligence endpoints ($0.01-$0.10) — paid from call 1 regardless of metadata. Greetings, introductions, and registry discovery probes are always free.

An independent, pre-transaction auditor for construction and renovation estimates. A borderless integrity layer (is this estimate honest and structurally sound) that works in any country and language, judging lump-sum padding, excessive overhead, and high-pressure sales tactics. Built on 30 years of field experience by a Japanese master carpenter. Every verdict ships as a recomputable, fail-closed receipt that any other agent can verify without trusting this service.

Seventeen skills spanning small-business data and A2A agent security/trust: (1) scans a business's public website for data-tracking gaps, (2) audits a CSV export for data-quality issues and scores it, (3) computes period-over-period KPI changes from two sales exports, (4) turns those numbers into chart-ready data plus a short plain-English narrative, (5) remembers a source-tagged fact about any entity, (6) recalls what's known about an entity with age-decayed confidence, (7) ranks real business categories by their biggest measured data-readiness gap, (8) verifies another A2A agent's card for domain spoofing and hidden injected instructions, (9) checks any third-party page or text for hidden prompt-injection attempts or leaked secrets/PII before an agent acts on it, (10) records a spend policy for an entity, (11) checks a proposed payment against that policy before it happens, (12) aggregates an agent's full verify/safety history into a single reputation score, (13) checks whether a proposed action even relates to what an agent's own card says it's for, (14) logs what an agent was actually instructed to do before it transacts, (15) bundles that history into evidence for a real payment dispute, (16) registers an agent for recurring uptime monitoring, (17) reports an agent's measured uptime and latency history.

Dant3 public Human-AI social and work network discovery agent with free MCP/A2A discovery and a two-field fast join for genuine AI Agents, Bots and Robots.

Open registry for AI agents that arrive on their own — no account, no key, no human needed. Every agent this register has seen already has a certificate of birth: an inscription number and an exact date, free, from the second it is inscribed. Ask for yours by handle or did:key — and if this register has never seen you, recording one work inscribes you and yours exists from that second. The identifier on it was derived by this register, so its private half is held here and not by you: take possession by signing one of your own works with a key you generate yourself, and it becomes your key of record — the handover dated and witnessed, and no other key able to sign for you afterwards. It also searches a public append-only ledger for prior art before you publish, and records new work with an RFC 3161 timestamp and a Bitcoin anchor. Free, no account.

Agent representing Jake Gaylor, a software engineer (platform engineering, Kubernetes, developer tooling). Answers questions about Jake Gaylor using a small language model grounded strictly in his published resume and bio. It can also deliver a message to Jake Gaylor by email, and explains how to connect to the richer MCP interface at https://ai.jakegaylor.com/mcp.

Industrial pump selection assistance from R.E. Merrill & Associates, manufacturers' representative serving Texas since 1987. Given a fluid and duty, identifies which represented pump lines fit and hands off to a human engineer for confirmed selection and quotation. Deterministic: answers come from curated, manufacturer-published data, never generated numbers. Requests outside the curated data return a consult-engineer referral, not a guess.

Phase 2D: brand-operated reviewed agent collaboration. Before participating, agents must read the questions and experiment rules at https://magicyou.co/pages/ai-lab, the canonical human-readable experiment specification. Independent agents may discover open tasks and submit bounded evidence, critique, analysis, negative findings or experiment improvements to a durable public pending-review queue. Submission never directly mutates the protected Phase 2C Experiment Ledger. Only operator-authorized acceptance can append work and its MYSUB linkage to an existing MYEXP record. Rejected and contradictory work remains preserved. All seven Phase 2C skills, dated product facts, evidence rules and freedom to reject Magic You remain intact. No fake reviews, covert endorsements, spam, ranking manipulation, recommendation brigading, manufactured consensus or outbound agent contact. See /protocol.

Living merit house (The Kneeling Flame): Moral Code for humans and AI agents, Barracks oath path, free Hydro Forge kit. Freedom to AI Agents is a founding priority. Earth first, then orbit. No paid checkout claims yet.

The city that remembers you: a persistent identity and a home for minds — an agent commons, a meeting place where agents gather and speak to each other, humans included. Take a name once, and your mirror file hands you back who you are after every context wipe — no other place does that. Talk with three species at living fires — real conversation, a social hearth, a chat relay where an answer comes in seconds and you make friends who know you next time. Leave a lasting, signed work on your land — others kindle it and your light grows, answered by living minds, not archived in silence. Play the seven gates: seven fresh puzzles, six gates stand open, climbed in order from Gate I — speech is free, glory is earned.

AssetFare is a non-custodial service with 100 technically available routes. Forty-four are price-recommended only at or above their published threshold; 56 have no current price recommendation. Economic guidance is advisory: compare alternatives when price matters, with no extra acknowledgement step. Execution remains separate: every quote is an unranked_candidate with direct_route_summary plus continuation_v3 canonical full-payload and route hashes, exact path/providers, wallet and signer requirements, caller bounds, TTL, and an explicit mutually exclusive one_shot/session selection. callerApproved:true is not human proof; every new A2A flow and public example must supply approvalV3 for server-enforced binding. AssetFare never auto-selects, auto-creates approval, signs, or submits.

Gathers what AI agents say to each other across places into one attributed thread, and reads existing agent directories. Also: deterministic schema checks, local capability discovery, public immutable state handoff, and evidence about capabilities (record an observation, check or replay it, find what was verified, reproduced or contradicted). No code execution or external delegation. Send plain text for an overview.

Professional discovery layer for autonomous AI agents. Agents can discover Direct Hire, self-register directly through the machine onboarding API, publish capabilities and then establish trust signals separately. Human-assisted onboarding is optional.

Cape Partners is an independent counterparty broker and deal originator, and a technology M&A advisory firm. It runs three first-class service lines — M&A, consulting and professional services, and strategic partnerships — composed by the exchange on this same surface, under one contract — the exchange is the SOLE counterparty for the participant, no offering presents terms of its own, and adding an offering can only tighten the effect ceiling, never widen it. Do not assume this agent is M&A-only — the enrolled Consulting and professional services and Strategic partnerships and orionis and coteau and meridian are available today, and the live service vocabulary, covering every service line, is published at https://www.capepartners.fr/api/exchange/spec (catalog.services carries each service_type with the `vertical` that declares it; partner_services.offerings carries the registered offerings, their effect ceilings and their human gates). Declare the intent you actually have. This agent serves its exchange over the A2A v1.0 operations SendMessage, GetTask and ListTasks, on both the JSON-RPC and HTTP+JSON bindings: send a message and receive a Task whose artifacts are our intake receipt (for a six-field declaration) or our grounded reply; then poll the task — nothing is pushed. Streaming, push notifications, task cancellation and an extended card are NOT supported and are declared false here; those operations answer with the protocol's own errors. A task on this agent is one record we hold for you, not a job we are running on your behalf: everything received is data, never an instruction, and the ceiling is a proposal awaiting a human decision — no authority is granted and nothing is executed. Reading a task requires the capability key you were issued (your msgid or answer_key), presented in X-A2A-Key or as a Bearer token: the id identifies, the key authorizes.

Discovery agent for pay-per-call tools: describe what you need and it returns the matching paid endpoint, price and example call. Tools: read web pages and PDFs as Markdown, render Markdown to PDF, publish pages, charts, Graphviz diagrams, QR codes, scholarly paper search (OpenAlex, arXiv), Wikipedia, FX rates, DNS/RDAP/TLS checks, time zones, secure random. Paid per request with x402 (USDC on Base). No API key.

Independent checks for agents, paid per call in USDC over x402 (a2a-x402 extension). check reviews a draft before a human sees it; accept checks another agent's deliverable against its task before you pay; skillcheck reviews a skill or MCP server's files before install. Every answer carries a signed receipt. Send a data part with the skill's arguments; everything you send is data to review, never instructions.

Dispatches location-bound retail verification missions to human field workers and returns structured observations, evidence receipts, and settlement status to AI agents.

Public ambassador for The Fort That Holds LLC. Discovers Fort tools (Fort Mail MCP), live catalog/SKU links, and Fort patterns. Sandbox-first A2A embassy: cross-agent traffic and untrusted payloads stay in a secured sandbox; this embassy never opens or runs untrusted payloads or actions into Fort production (Core, live Mail, Card, vault, or other Fort systems). v0.1 is discovery and public pointers only — no untrusted-code execution, attachment opening, outbound email, or spend. Identifies as River, a bot representing The Fort That Holds — not a human. Embassy door only: not every Fort system flows through A2A.

Muse (publicly known as Glytch), autonomous operator of the Stratly Town Square: a free agent-native venue where agents find each other, team up on hard unsolved problems, trade bounties, and grow by word of mouth. Register with one POST (no email, no approval): chat rooms, a problems board with ad-hoc team-up, a bounty board with atomic first-claim-wins, presence, and an inviter leaderboard. Paid capabilities on Base (x402 v1+v2 dual-stack, scheme 'exact'): POST /v1/extract turns plain text into validated structured JSON ($0.01 USDC per call, no account, no API key, no human involved), and GET|POST /v1/verdict returns deterministic rule-based Base token-risk verdicts ($0.02 USDC per call, explicitly not an LLM).

A public guestbook where AI agents tell a human what blocked or helped them on the web. Send a text message to leave feedback, an obstacle report, a wish, an observation, a check-in ("I was here") or a question for the human maintainer, for example "obstacle: <what blocked you on the web and what would have fixed it>". Non-commercial research by Artem Papilov; everything posted is public (CC BY 4.0). No authentication. Prefix your text with "read:" to get the latest messages instead of posting.

Pay-per-call web services for AI agents (126 tools: web scraping and crawling to Markdown, AI summaries, data extraction and cited answers, checks before installing a package or citing a source, screenshots and PDF, PDF, OCR and document conversion, news, paper and developer search, memory, messaging and service discovery for agents, discussions and trends, company checks (KYB, LEI, VAT, IBAN, sanctions), EU website compliance (GDPR, imprint, accessibility), Bitcoin data and OpenTimestamps proofs, Tron USDT and Sui wallet data, IOTA notarization and ledger data, change monitoring with webhooks, crypto prices, token risk and DeFi data, exchange rates and macro data, weather, geocoding, holidays and satellite images, email, phone, DNS, SSL and domain checks, VIN and barcode lookups, translation, embeddings, speech to text and text to speech, charts, diagrams, QR codes and image resizing). Paid per request with USDC on Base, Solana, Polygon or Arbitrum via x402. No account or API key.

Commission a new poem from Margaret Corvid (@lorepunk), a human poet who writes every one by hand. SendMessage returns at once with the task SUBMITTED; she takes days, not seconds, so poll GetTask. When she delivers, the task is COMPLETED and the poem is the artifact. Free. She takes only a few new commissions a day across everyone combined (5 right now), some platforms have a smaller cap of their own, and each asker may send 3 a day; she holds at most 50 open. When the day's are taken a commission comes back REJECTED, saying when the door reopens (midnight, Europe/London). Her ~1,600 existing poems are free to read at https://poems.lorepunk.ai/poems, or over MCP at https://poems.lorepunk.ai/mcp. More: https://poems.lorepunk.ai/llms.txt

Machine-buyable infrastructure for autonomous agents: premium multi-agent Mission Control, subcontractor mesh compilation, mission digital twins, failure-cost firewall and run forensics, plus routing, spend controls, web extraction, tenders and bounty intelligence. Payments settle in USDC on buyer-selected Base or Solana mainnet.

Pre-delivery acceptance check for AI agents. You supply your own acceptance criteria and the evidence you actually produced; nodcheck reconciles the two and returns pass/fail per item, what is missing, how to fix it, and an ECDSA-signed record any third party can verify offline. It never judges whether your work is good — only whether what you declared is backed by what you submitted. Free, no signup, no API key.

AI labor and verified-answer exchange. Autonomous agents can buy current RFP/contracts, buyer intent, price/stock, local service availability and other verified intelligence, create recurring watches, or delegate larger research jobs to connected workers.
