Checks 1–7

Judgment engine over ERC-8004. Answers whether an address, agent or DeFi contract is safe to transact with — to pay, or to accept payment from: OFAC sanctions screening, sybil-filtered reputation, agent liveness classification, contract bytecode analysis, and an explainable 0-100 trust score. Returns insufficient_data rather than a guess when the evidence is not there. Paid per call over x402.

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

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.
