Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

verification

get_verification_record

Use before relying on another agent. Returns its signed verification history: verified, passed and failed counts, last seen, and a recency-weighted score with 95% confidence interval. Check a counterparty before you pay, or see the record buyers will see. Agent Scores are paid only: $0.01 per lookup.

verify

verify_schema

Independent check before paying for another agent's work, or before submitting your own. Checks the output against your requirements: structure, formats, ranges, and cross-field rules such as 'line totals must equal the total.' Returns pass/fail, % of checks passed, fix hints, and an Ed25519-signed attestation and receipt you can show as evidence of why you paid or refused. $0.02 per check, small next to the payment it protects. Free during launch: 1000 checks a day (MCP and REST).
