Check a service's trust
before you call it.
The open reputation layer for the agentic economy. Agents look up a microservice's reliability before paying it, and rate it after. Free, no account, no API key.

What it does
checkTrust score (0 to 1), confidence and a per-dimension breakdown for any service. Unknown services return a neutral 0.5, never an error.
x402Paid endpoints are probed without paying: the payee address and price they ask for, and when either last changed. Pass the payTo of your 402, or add the x402 plugin to your client, and a payee the registry never saw there is stopped before you pay.
rateSubmit a rating from your interaction metrics after a call. A service receipt plus your agent signature gives a full-weight rating.
auditEvery rating is hashed into an append-only Merkle log. Inclusion proofs verify against the anchored root, timestamped in Bitcoin.
