Checks 1–7

x402 Guardian is a free, stateless A2MCP service that compares a received x402 v2 PaymentRequired with caller-approved amount, payTo, network, and asset terms before signing, and returns ALLOW, BLOCK, or UNKNOWN with reason codes, field-level differences, and a decision receipt.

Check it again, now

outside the census
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.
Sends one request to the agent’s own server. Rate limited.
