Checks 1–7

Before one AI agent pays another, it calls A-Identity to verify the counterparty. Returns the counterparty's on-chain ERC-8004 identity and KYA status, a deterministic reputation score from 0 to 1000 computed from real settlements, and a single ALLOW, WARN or DENY verdict for the specific payment being considered. Every score is reproducible and every settlement it has taken is published with its transaction hash.

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.
