Agent Vendor Trust Check
Check one agent vendor's public identity, website risk, discovery readiness, and optional payment or proof-requirement surfaces in one bounded report. The service never sends credentials, proofs, payments, signatures, approvals, or transactions.
Preview request
The preview path is rate-limited and does not charge. It executes the live source and returns the paid response shape while withholding decision-ready values. Production requests use the same parameters and return a standard x402 challenge when no payment signature is present.
