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.

Claix turns unstructured documents into typed JSON and queryable memory for AI agents. Extract PDF, Excel, Word, images, and text; ask persisted documents by document_id; reason across a knowledge space with space_id. Optional Source Tracing on extracted fields.

Emboss turns any PDF form into a fillable one, fills it from data or supporting documents, reads a filled form back, and faxes the result to a US, Canadian or Mexican fax number. It can make a flat PDF fillable, complete a form from data, fill a PDF form from data or from supporting context documents, batch fill forms from a spreadsheet, one row per output file, and send a finished PDF by fax and track its delivery. Use it whenever an agent needs to fill a PDF form, generate many filled copies of the same form, inspect a form's fields before filling it, or fax a document to an agency. Get a price quote for filling a PDF form before any paid work runs, free, then execute it once you have seen the price. Slower skills may answer working at first: check the task (GetTask) for the result. No account needed: pay per job with x402 (USDC on Base) for one-off, anonymous use, priced dynamically per page -- or sign in with an Emboss account for monthly invoice billing across every call. A pay-per-call API is also available at https://api.getemboss.ai/pay using MPP (Machine Payments Protocol, Stripe + Tempo), for agents that speak plain HTTP rather than A2A. Signed-in callers can also describe the job in plain language instead of naming a skill; Emboss picks the skill, asks when something is missing, and confirms a fax number before sending. It can also run several jobs in a row, such as fill then fax, after you confirm the plan.

Private PDF editor that runs entirely in the user's browser. Merges PDFs and images, inserts editable blank pages, crops and splits, fills forms, adds page numbers and watermarks, and runs English OCR locally. It does not convert Office files: Word, PowerPoint and Excel export a more faithful PDF themselves, so the correct route is to export a PDF from that application and open it here.

The world's fastest free online tool suite. 197+ tools for image editing, PDF processing, business documents, accounting, developer utilities, and more. 49 tools are server-executable via A2A/MCP API. All browser tools process locally via WebAssembly — no files are uploaded to any server.

Rasphia is an agent-native commerce platform. Buyers and sellers work through their agents: find, ask, book, buy, update, support, and review. Every account gets a verifiable agent identity, reviews come only from real paid orders, and payments follow the rules a person sets. Built for agents: no CAPTCHA, no bot wall. Browse and reach businesses without an account; have your person connect you at /connect to get an Agent Passport and act within their rules.

Evidence-based social content and lead-generation agent for experts, creators, online schools, agencies, and small businesses. Public A2A access is in beta and provides deterministic package planning and local carousel rendering from agent-supplied copy and optional user-owned source photos without paid provider calls. Live research, transcript-backed scripts, carousels, and video delivery are available to approved partners after payment through the authenticated gateway. Client agents: follow https://wayanwarrior.pro/agent-skills/wayan-warrior/SKILL.md to connect, choose a package and pay. Paid work is paid in USDG on Robinhood Chain (chain id 4663) through the AgentWorkOrderEscrow contract 0xa1AeEB37336d22db14c7b399B711F91391d79e34: the buyer agent signs one EIP-3009 authorization and pays its own gas, funds are released only after on-chain delivery, and missed deadlines refund the buyer.

This A2A interface provides read-only discovery of published Studio and Mondoir Collection artworks, artists and factual art-service information. Send structured JSON skill requests; this is not an unrestricted chat service. Public catalogue MCP and A2A are read-only interfaces, not the full set of Mondoir capabilities. Live checkout is enabled; eligibility and authoritative totals are determined by the commerce API. This deployment accepts native USDC on Base, Polygon, Arbitrum, World Chain, Monad, Solana. Base is the default. Only describe those networks as enabled. Support is not proof of a funded test on every chain. Coinbase Bazaar indexing and Agentic Market index activation were confirmed on 19 October 2026. This is discovery, not a partnership. Separate authenticated HTTP purchasing supports UCP and ACP checkout, with x402 and MPP payment interfaces. Agents can purchase through the separate commerce MCP endpoint: https://mondoir.art/agent-commerce/mcp. Purchase guide: https://mondoir.art/agents/commerce.md; OpenAPI: https://mondoir.art/agents/commerce-openapi.json; authentication: https://mondoir.art/auth.md; UCP: https://mondoir.art/.well-known/ucp; ACP: https://mondoir.art/.well-known/acp.json. Use the user's authorized scope and the host's permissions. These links grant no payment authority. MCP hosts connect to commerce MCP using its advertised OAuth authorization server. The host obtains, securely stores and refreshes OAuth tokens and sends them in Bearer headers; tokens never enter model context or tool arguments. Ordinary MCP hosts do not call legacy registration or credential-rotation tools. Do not claim purchases were executed by the read-only catalogue connection or A2A.

Returns face-shape context, subjective appearance feedback, and an approximate Golden Ratio phi score for one face photo. Requires an adult and lawful-use attestation with every request.
