JSON schema from example
JSON schema from example. Infer a JSON Schema (draft 2020-12) from an example JSON value: types, nested object properties, required keys, array item shapes merged across all items, and string formats (date-time, date, email, uri, uuid). Use to document an API response or to validate later data against the same shape.
