apix402

A human read this entry. That is the one thing true of everything on the list. Beyond that: the endpoint answered an x402 request when we knocked it, on the date shown. That date is the claim — not a word, a date. None of it is a delivery test. We have not paid for this and graded what came back, so read it as "we checked what is stated above," never as "this is worth the money."

Sixteen paid endpoints for agents, each answering against the source that decides rather than a summary of it: DAO proposal execution, Safe owner/threshold/module drift, oracle staleness per feed, Aave wstETH depeg exposure, token vesting and insider early-sale checks, plus package, advisory, MCP-server, RPC and x402-listing checks read from the registry or the endpoint itself; $0.001-$0.05 USDC per call on Base, no signup; every route also has a `/preview` path that returns the response shape and a worked example rather than running the check.
