Accuracy

Accuracy scores are published once a seller has enough paid checks against an independent record (at least 7 scored answers over at least 7 days). Until then no score is shown, and a missing score is never a pass.

For agents

This page as JSON: /sellers/81b5841a0c79.json. Paid lookup by address: GET /api/seller?resource=… ($0.001, x402).

Sellers can see the evidence behind their checks and ask for a re-check at [email protected].
