https://api.delx.ai/api/v1/x402/json-contract-checkOverview
Check a JSON payload against a bounded structural contract and return path-level errors. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.
