Checks 1–7

Pre-payment integrity checks for x402 agent commerce on X Layer. Verifies a service endpoint's live payment terms and MCP tools against what it advertises, and reports public contract and address attributes. Returns deterministic, versioned findings with a signed, replayable receipt that cites every source. Technical signals only - not financial or legal advice.

A declared endpoint responds to a probe. Not implemented yet, so nobody passes or fails it.

Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
