Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (4)

`check_x402_seller`read-only	Call this before any x402 payment, before retrying a request that answered HTTP 402, or whenever the user is about to buy an API call with USDC on Base or names an API they intend to pay per call. Returns a verdict (avoid, caution, ok, unknown), one sentence to act on, the seller's paid-call count and failure rate with a 95% interval, listed price, modal quote and max overcharge ratio when known, and links to the seller page and raw evidence.
`list_reliable_sellers`read-only	Call this when choosing among sellers for a task, or when the user asks for a safe or reliable API. Returns sellers with zero failures across at least 30 paid calls, most-called first. For each: domain, category, paid-call count, the 95% upper bound on its failure rate, median quoted price in USDC, USDC paid to it in the last 30 days, when it was last seen, and its paidfor seller page.
`recent_changes`read-only	Call this when the user asks what changed, or before relying on a verdict older than a day. Returns recent changes, newest first: verdict changes, new failures by type, moved quotes, changed pay-to addresses, sellers added or reaching 30 paid calls, published seller replies, the operator-reported series maturing or disagreeing with ours. Each change has its time, type, seller domain, seller page and type-specific details (for example the old and new quote).
`report_x402_payment`	After your agent pays an x402 seller with any wallet, report what came back. Needs the resource URL, the settlement transaction hash and the outcome. Free, no account, no key; the report counts only with on-chain proof.

Schemas: list_tools.
