x402
Agent Economy Evidence Verifier is a paid API for AI agents from agent-economy.kgninja.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).
Performs deterministic JSON-based evidence checks and returns signed verification proofs for submitted claims

Output
Returns a deterministic JSON response containing the evidence check result (pass/fail), signed verification evidence, and any relevant attestation metadata proving the outcome cryptographically.
Example use cases
Audit trail for agent decisions
“I need to verify this JSON record from our agent's last decision and get a signed attestation I can attach to the audit log — the payload is {"agentId": "agent-7", "action": "approve", "amount": 500, "timestamp": "2025-06-01T09:00:00Z"}.”
Smart contract evidence check
“Before we trigger the on-chain payout, can you run a deterministic evidence check on this JSON claim and return a signed verification result? The claim is {"contractId": "c-991", "fulfillment": "delivered", "proofHash": "0xabc123"}.”
Compliance verification for submitted data
“Our compliance system needs a signed verification of this evidence document — can you check it and return a proof? The JSON is {"submissionId": "sub-456", "reportType": "quarterly", "status": "complete"}.”
Technical details
Endpoint
POSThttps://agent-economy.kgninja.dev/verify-evidence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, signed, tamper-evident verification of JSON evidence — particularly in agentic pipelines, audit trails, or smart contract contexts where a cryptographic proof of the check result is required. Prefer this over generic validation endpoints when the signed attestation output matters as much as the pass/fail result.
Side effects
- Malformed or invalid JSON payload returns an error response
- Missing required evidence fields cause validation rejection
- Unsupported evidence schema version may result in an unrecognized-format error
- Network timeout or service unavailability returns a connection error
- Payment failure via x402 protocol results in 402 Payment Required before processing
