Payload Completeness Checker

Payload Completeness Checker helps verify whether a JSON payload is ready for submission based on a provided required schema. Use it when you have a payload object and a required_schema object, and want to check whether required fields are present and whether basic expected types match. The app returns a structured result showing whether the payload is complete, which fields are missing, and which fields have type mismatches. It is read-only. It does not submit payloads, call external systems, store user data, modify data, fix the payload, or make business decisions.
