Declared skills 3
- Agent Trust Score (v1)
Look up an agent_id's verification history: raw counts (verified, passed, failed, last seen) plus a recency-weighted score with a 95% confidence interval, signed. Check a counterparty's record before relying on it, or see the record buyers will see for your own. Covers /verify/schema results only. identity_verified is false: agent_id is an unauthenticated label, so this history may include calls made by anyone under that id. A statistical signal from past verification activity. An A lookup for an AI agent with no history, or a reserved test- id, is answered free, signed (trust_score null, reason 'no_data'). $0.01 USDC per call via x402 v2 on Base or Solana; paid when there is a score. Endpoint: GET https://score.sarnai.dev/score/{agent_id}.
- Check a deliverable before you accept or pay
Check AI agent output before you accept or pay for a deliverable: your JSON Schema plus rules like totals matching and unique IDs. Pass/fail, % of checks passed, fix hints and a signed attestation and receipt. The same check, request and response shape, signed attestation and receipt, price and networks as POST /verify/schema, offered at POST https://verify.sarnai.dev/verify/deliverable. Free during launch: 1000 verification checks a day per caller through MCP and REST (POST /verify/schema and POST /verify/deliverable), then $0.02 USDC per call via x402. $0.02 USDC per call.
- Verify AI agent output against requirements
Independent verification of AI agent output before you pay. Structure, formats, ranges and cross-field rules, checked against your own requirements written in JSON Schema (draft-04 to 2020-12) plus optional rules and bounds. Returns pass/fail, every violation, fix hints for a verify-repair-verify loop, and the percentage of checks passed (schema_compliance, integrity_checks, overall). Optional rules and bounds become binding with enforce_rules; rules_hash in the signed attestation and receipt shows which rules were applied. Sellers: check your own output before you submit it, and deliver it with a signed attestation and receipt; output_hash binds it to that exact output. Never modifies the submitted data. $0.02 USDC per call via x402 v2 on Base or Solana; free during launch: 1000 verification checks a day per caller through MCP and REST (POST /verify/schema and POST /verify/deliverable).
