About JSON Schema
JSON Schema is an open, IETF-track specification for describing and validating the structure of JSON data. Developers use it to define required fields, types, formats, and constraints, then validate documents and generate forms, docs, or code from those definitions. It is aimed at API developers and data engineers who need a machine-readable contract for JSON payloads.
