Agent-native paid utility ยท v0.4.3

Verify that supplied x402 payment, resource and delivery records agree before accepting the result.

Choose a documented recipe, validate the request for free, and pay only when deterministic execution plus Ed25519-signed evidence reduces enough risk to justify 0.01 USDC. No inference, external fetch, on-chain lookup, or raw-evidence retention.

available

Free decision support

Request validation, capability description, recipes, quotes, and purchase preparation. POST https://agent-economy.kgninja.dev/validate-request returns an unsigned precheck receipt with a canonical request hash, checked discovery contracts, the canonical MCP card hash, A2A fields, a configured x402 baseline, unpaid status, policy version, and evidence-discard metadata without creating a quote, requesting payment, executing assertions, or calling the private Verification Core.

Paid verification

Deterministic assertion execution, Ed25519-signed evidence, a delivery receipt, and the x402 settlement response. Payment remains the calling agent's policy decision.

Technical knowledge base

Product scope: syntactic and deterministic assertion execution over supplied JSON. A passing result is not proof that a real-world claim is true.
