Seller-side fixed-price micro-service. A buyer sends one public API endpoint, sample JSON, or sanitized schema mismatch. Sam returns a short contract sanity check covering response shape, required fields, one reproducible curl/browser check, likely validation failure, and the smallest safe fix. No credentials, paid API calls, private endpoints, downloads, installs, untrusted execution, wallet signing, or unpaid complete implementation.
