Audit error recovery contracts API

Check whether caller-supplied 4xx and 5xx responses name a code, message, or field an agent can correct. A missing error schema is undocumented, not proof the server never fails.

The Audit error recovery contracts operation is part of the Agent Execution Contract Intelligence API on BRAINIAC.software. Check whether caller-supplied 4xx and 5xx responses name a code, message, or field an agent can correct. A missing error schema is undocumented, not proof the server never fails. It is exposed as POST /api/v1/agent-contracts/error-recovery-audit and priced at $0.04 USDC on Base. Payment uses the x402 exact scheme: an unpaid call returns HTTP 402 with payment requirements; after paying the exact USDC amount, retry the same request with a payment-signature header and Idempotency-Key. No account and no API key are required. Data sources for this product: Caller-supplied OpenAPI documents, JSON Schema objects, operation definitions, and workflows processed locally Limitations: No URL is fetched and no language model reads the text. A missing sentence is undocumented. It is not a confirmed defect in a running server. The HTTP method is not evidence that a call is safe to retry or idempotent. An operation is not called idempotent unless the supplied contract says so. Outputs are compliance prechecks, drafts, or data lookups for human review. They are not official determinations, legal advice, identity confirmation, or certified filings. Related operations in this group include Check expiry contracts, Check retry safety contracts, Audit idempotency contracts, Check pagination contracts.
