Is agent402 live?

Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.

Is agent402 free to use?

Partly — some of its tools are open, others need a key or payment.

What tools does agent402 have?

17 tools: payment.info, memory.write, decide.execute, catalog.call, demand.request, decide.feedback, catalog.search, server.describe, ….

Is agent402 safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• catalog.search reads open 7d ago

  Keyword search over the Agent402 catalog of 500+ tools (625 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 McpClient pays automatically), or npx agent402-mcp with a wallet.

  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 and params it lists.

• web.search reads auth-required 6d ago

  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 = past day/week/month/year). Start here to DISCOVER pages, then read the winner with extract.

• web.answer reads auth-required 7d ago

Returns clean prose plus a structured citations array (URL, snippet, favicon) - backed by an independent search index, not the model's training data. Useful when an agent needs a synthesized answer plus the receipts to verify or follow up.

• browser.render reads auth-required 7d ago

  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 pixel evidence use screenshot.

Exact-key storage for structured state. For retrieval by MEANING rather than key, use the catalog slugs memory-remember and memory-recall (on MCP, through catalog.call with that slug).
