description: >-
  JSON Schema is a vocabulary for annotating and validating JSON documents,
  widely used for defining API request and response shapes across REST APIs.
  The current stable specification is Draft 2020-12. JSON Schema differentiates
  between the instance being validated and the schema document containing the
  validation rules, and supports URI-based references for recursive and
  cross-document definitions.
