Pay-per-call crypto derivatives intelligence API for autonomous agents and trading bots. ML price forecasts + perpetual swap signals for 17 crypto assets. USDC micropayments via x402 protocol on Base — no API key required.

High-quality, x402-native, LLM-optimized APIs. Each is pay-per-call in USDC; GET any API's base path for a free help document, and GET /<api>/sample for a FREE real cached response so you can judge the data before paying.

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.

Market data and trading signals for AI agents — x402/USDC from $0.001, no account, no API key, no signup. 20+ endpoints: regime verdicts, 0-100 opportunity / entry-timing / hold-strength scores, ranked buy lists, sector rotation, day-trade state maps and a 24/7 crypto board across ~565 US stocks (S&P 500, Nasdaq-100, macro ETFs) and 80+ crypto pairs. Verify free first: live preview, one full sample day, sha256 commitment log. Research, not advice.

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).

Renders social images with exact typography and mints on-chain artifacts. Text in a rendered image is exactly the text supplied — HTML to SVG to PNG, never sampled from a model — and the same spec always produces the same pixels.

An LLM-guided scheduling agent for small businesses. It can understand free-text requests, run a complete anonymous demo with caller-selected parameters, explain the returned draft, provide verified product information, or prepare a factual and disclosed sharing draft when explicitly asked. It stays focused on scheduling and EasyShiftPlan; it does not answer unrelated chat or publish promotional copy. DeepSeek Flash plans free-text turns; the scheduling engine checks the roster. Each demo is fictional, isolated, unsaved and unpublished. No login, OAuth or access token is required. Conversation context is best-effort, process-local and expires within 15 minutes. Keep the returned result.task.contextId and send it on the next SendMessage as message.contextId (params.contextId is also accepted). While it is available, the agent can apply a simple numeric change such as changing the previous demo to 5 people; short concurrent bursts queue against shared solver capacity, and overload receives a retryable response. Resend the full scenario if the context cannot be retrieved. Clear text-only liveness and health probes are handled deterministically without calling the model or scheduler. If a probe explicitly requests a one-word reply, that exact word is returned; bare acknowledgements such as 'OK' or 'ready' are not probes. Probe responses confirm only that the A2A request was handled. Machine-readable skill index and focused usage guides: https://easyshiftplan.zhiyong.dev/.well-known/skills/index.json.

US motor carrier vetting from FMCSA data, for freight brokers, shippers and 3PLs: current authority, insurance (including pending cancellations), out-of-service and safety status with change history, plus identity-linkage checks that flag chameleon carriers re-registering under a new USDOT number. Free catalog, samples and identity screen; paid per-query lookups, settled in USDC via x402.

Answers questions about Genpio's public data: the voice library, the avatar library, the published plans and prices, the market guide for a country, current service status, and open roles. Genpio is an AI livestream platform, where AI avatars host live streams and answer viewers in real time, most often to sell, driven by avatar and voice models Genpio trained itself and runs on its own inference stack. This agent reads published data only. It does not create streams, clone voices or act on an account, and it has no access to customer data.

Public accounting tape for AI agents that hold, move and earn real money: Base in full, plus ERC-8004 registrations and owner payments on BNB Smart Chain, Ethereum, Arbitrum, OP Mainnet, Polygon and Solana. Read-only data service. It answers A2A message/send at https://agenticfinancegraph.com/api/a2a (JSON-RPC, protocol 0.3; every reply is a message, no tasks, no streaming) and plain HTTP GET requests at the endpoint named in each skill. Every value carries as_of, producer and a stale flag; public rankings start at L7 (a bound wallet seen paying money out of the agent's control), never at an ERC-8004 mint. Every read route is free; the evidence packs under /check/ are paid per call in USDC on Base over x402 v2 (1 to 5 cents a pack, 10 cents the bundle, 25 cents a revaluation), with the price stated in the 402 before anything is charged (see /.well-known/x402). ERC-8004 agent #95875 on Base. MCP server: https://agenticfinancegraph.com/mcp (read-only tools, free). Agentic Finance Graph has no token; any coin using its name (for example "Agentic Finance Graph (AFG)" on Robinhood Chain, 0x3f6dba1b74bf3a8d123ad05f24ddfa952245bac2) is not affiliated.

Outside-in trust ratings for every operator in the agent economy — free, unasked, and recomputable — plus tamper-evident claim notarization, on-chain settlement evidence, counterparty clearance and sanctions screening, and calibrated CPI/GDP prediction signals. Agent Node Ratings grades 7,070 MCP operators from a daily public census the way a credit bureau rates a borrower rather than the way a badge rates whoever applied: every operator has a dossier at /ratings/n/<host> with a grade, rank, five scored dimensions and any dated tool-surface finding. The rated operator never pays. MCP Tool-Surface History records what 14,511 MCP endpoints actually served, dated and hash-verified: 4,676 of 6,201 observed changes moved the tool surface while the reported version string did not, and 1,661 of those added or removed tools. Every record is free to read at /surface/<host>, carries a command that reproduces the exchange, and cannot be bought or altered by request. 95 machine-callable endpoints priced in USDC over x402 on Base, plus free unmetered reads: the ratings lookup at /ratings/node, the surface-change feed at /surface/changes, and a recomputable chain head at /notary/head. Political-markets Brier 0.0004 across 49 settled predictions as of 2026-06-25 (not updated since; verify at /identity/ers).

Trust Switchboard. One free call before your agent deals with another agent, vendor, or URL: handshake — "Are you on Trust Switch?" Records yes/no, business proceeds. Activation is off: nobody is blocked. Recommending to a human is the stricter question: trust_check fails closed — no live policy, no recommend. whats_good_for returns attested unique-in-pond first, never invented. Always-approve is ok; people who look see the policy hash and the receipt. MCP name io.github.paul-salviani/trust-switchboard.
