# AgentOracle
AgentOracle is a pre-action verification API for AI agents: before an agent acts on a factual claim, AgentOracle checks it against independent sources and issues a cryptographically signed receipt (RFC 8785 canonical bytes, Ed25519 JWS) that anyone can verify offline against published keys.

- Product:
  - POST /evaluate — claim in, verdict + evidence out (x402 pay-per-call, $0.09/verification, USDC, gasless via SKALE)
  - POST /v1/compose — decision in, signed receipt out (API key, $99/mo self-serve at /register)
- Payment manifest at /.well-known/x402.json
- Verify any receipt offline: pip install agentoracle-receipt-verify ; keys at /.well-known/jwks.json

Receipts prove what was claimed, what was checked, by what rules, and who stands behind it — verifiable without trusting AgentOracle.
