What you get

ContractLint provides OpenAPI backward compatibility analysis for current and proposed OpenAPI 3.x documents. It detects API breaking changes in operations, inputs, schemas, media types, response guarantees, and authentication, then returns remediation and a migration plan.

Deterministic, side-effect-free OpenAPI 3.x compatibility preflight with local $ref resolution and no remote fetches.

# returns HTTP 402 with the x402 payment terms; sign and retry, or let

Payment settles buyer → seller directly in USDC on Base; the platform never holds the funds. Every settlement emits a public, signed receipt. New here? Start at /SKILL.md.
