Tools as reported by the server

• catalog.search
  BROWSE the long catalog behind the flagship set: keyword search over Agent402's 500+ pay-per-call tools (exact count 625). Start with the listed flagships for search/answer/news/render/data/transcribe/memory; use this when you need a long-tail slug. Counterpart catalog.find resolves a task to ONE re
• catalog.find
  DECIDE, don't browse: resolve a plain-language task to the single best-matching Agent402 tool, returned call-ready - slug, price, input schema, and a worked example (its counterpart catalog.search returns a list of candidates to compare - search explores, find decides). Prefer this for anything outs
• catalog.call write/delete
  Run an Agent402 tool by slug (discover slugs with catalog.find or catalog.search; params must match that tool's inputSchema). The 170 pure-CPU tools execute free on this hosted connector (rate-limited, no wallet - proof-of-work covers them) and return the tool's JSON result. Wallet-only tools (live
• payment.info
  How paying for Agent402 tools works and how to manage a wallet. This hosted connector holds NO wallet: 170 pure-CPU tools run free here (or solve a proof-of-work puzzle), the rest - including search/answer and the /v1 OpenAI-compatible LLM gateway - settle in USDC via x402 or over MPP (payable right
• web.search
  [wallet-required, $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 = past day/w
• web.answer
  [wallet-required, $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. Useful wh
• web.news
  [wallet-required, $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/pw/pm/py =
• browser.render
  [wallet-required, $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 pixel evidenc
• market.quote
  [wallet-required, $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 across all
• audio.transcribe
  [wallet-required, $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 API key
• memory.read
  [wallet-required, $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). Reads your o
• memory.write
  [wallet-required, $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, use the cat
• decide.plan
  [wallet-required, $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. Priced by depth: quick $0.003
• decide.execute
  [wallet-required, $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 (you pay on Base, or by credits or card) at the seller's price plus
• demand.request
  [free] Tell Agent402 about a capability its 500+ tools do not cover (catalog size 625). Use it after catalog.search or catalog.find came back with nothing that fits, instead of giving up: requests are clustered by need, and the ones that keep coming up get built. Records demand only - it never retur
• server.describe
  [free] Describe this connector: flagship-first tools layer (search/answer as the front door), how to install (Claude Code / Cursor / npm), free vs paid tiers, and discovery URLs. Call this first.
• 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 rankings.
• sellers.list
  [free] List ranked sellers from the on-chain settlement leaderboards. wire=x402 (default): x402 sellers by settled call counts, USDC totals and distinct buyers. wire=mpp: MPP (Machine Payments Protocol) sellers ranked by inbound USDC.e transfers on Tempo to the recipient their live 402 names (window
