Qué puede hacer

Nombres y descripciones de las herramientas tal como los informó el servidor el 6 nov 2026. Los escribió el creador, no nosotros; los mostramos como texto sin formato.

• catalog.search

  Keyword search over the Agent402 catalog of 500+ tools (628 loaded by this connector). Returns { results, workflows }; run one with catalog.call. 170 pure-CPU tools run free here (proof-of-work). The others are paid per call, payable here over MPP (credential in _meta; mppx McpCl

• catalog.find

  Resolve a plain-language task to the single best-matching Agent402 tool, returned call-ready: slug, price, input schema and a worked example. Use catalog.search to compare several candidates. Returns { task, results } with the top pick first; run it with catalog.call and the slug

• catalog.call

  Run an Agent402 tool by slug, with params matching that tool's inputSchema; find slugs with catalog.find or catalog.search. The 170 pure-CPU tools run free here, rate-limited, through proof-of-work. Paid tools are payable here over MPP (the challenges ride in _meta). An unknown s

• payment.info

  How paying for Agent402 tools works. This connector holds no wallet: 170 pure-CPU tools run free through proof-of-work, and the rest settle in USDC over x402 or MPP (payable here). Covers wallet setup, per-call and session spend caps, the payment rails, and checking a wallet's ba

• web.search

  Paid ($0.01/call): Live web search: ranked results[] of {title, url, description (the snippet, plain text), age, publishedAt (ISO)} from an independent search index as clean JSON - fresh pages your model's training cutoff has never seen. Optional freshness filter (pd/pw/pm/py = p

• web.answer

  Paid ($0.08/call): AI-generated answer to a natural-language question, grounded in live web search results with source citations. Returns clean prose plus a structured citations array (URL, snippet, favicon) - backed by an independent search index, not the model's training data.

• web.news

  Paid ($0.01/call): Live news search: ranked recent articles as results[] of {title, url, description (the snippet, plain text), age, publishedAt (ISO), source (publisher hostname), breaking} from an independent search index as clean JSON. Same freshness filter as web search (pd/p

• browser.render

  Paid ($0.01/call): Render a page in a real headless Chromium browser (JavaScript executed), then extract the main content as clean markdown. Use this for SPAs and JS-heavy sites where plain fetching returns an empty shell - try the cheaper extract first for static pages; for pixe

• market.quote

  Paid ($0.001/call): End-of-day US equity quote: last close, day range, consolidated volume, previous close and the change between them. US equities only; indices, FX and crypto are not covered (crypto-price serves those). Built from the official consolidated end-of-day summary ac

• audio.transcribe

  Paid ($0.030/call): Transcribe audio to text with the gpt-transcribe model. Provide a URL to an audio file (mp3, wav, m4a, etc.) and get back the transcript. Add diarize:true for speaker labels, word timestamps and a language confidence score (the scribe-v2 model, same price). No

• memory.read

  Paid ($0.001/call): Read from a wallet-scoped namespace. ?key=… returns the stored value; omit key to list keys. The read half of memory-write's exact-key store. For similarity retrieval over remembered text, call the catalog slug memory-recall (on MCP, through catalog.call). Rea

• memory.write

  Paid ($0.001/call): Persistent key-value memory for agents, scoped to the paying wallet. Your x402 payment IS your authentication: the wallet that pays owns the namespace. No signup, no API keys. Exact-key storage for structured state. For retrieval by MEANING rather than key, us

• decide.plan

  Paid ($0.010/call): Describe a job and get a call-ready plan: which tools, across this catalog and outside x402 sellers with a recently verified 402, solve it end to end, in what order, with fallbacks and input params that validate against each tool's schema.

• decide.execute

  Paid ($0.001/call): Run a decision's plan (decisionId from POST /api/decide), or a free plan sketch (steps), through Agent402: first-party steps run directly, third-party steps are bought from the seller and resold to you at Agent402's price (paid with a wallet on Base; prepaid c

• demand.request

  [free] Report a capability the 500+ tools do not cover, after catalog.search or catalog.find found nothing that fits. Requests are clustered by need, and frequent ones get built. Records demand only: it runs nothing. Same intake as POST https://agent402.tools/api/wish; aggregate

• server.describe

  [free] Describe this connector: the tools it lists, how to install (Claude Code / Cursor / npm), free vs paid tiers, and discovery URLs.

• decide.feedback

  [free] Report whether one step of a decide.plan decision worked (success or failure, optional 1-5 quality and latency). Needs the decisionId and feedbackToken that decide.plan returned; one verdict per step, a later report replaces it. Reports feed tool reliability in future rank
