ReadyThis is a starter model inferred from one sample, not a complete contract.

Review optional fields, unions, nullability, numeric precision, naming conventions, custom scalars, validation rules, and framework annotations against your real API/schema before using generated code in production.

Trust and standards boundaries

Formatting is not schema validation, Base64 is not encryption, URL normalization is not a privacy guarantee, UUID metadata is not provenance, and decoded JWT claims are not trusted until cryptographic and application-specific validation succeeds. RS256 tools accept explicit PEM key formats and do not fetch issuer keys or make authorization decisions.

How to use this JSON to TypeScript

Turn sample JSON into editable TypeScript types while keeping inference limits and optional/mixed-shape uncertainty explicit.

What the generated code means

The generator infers a starter model from the values present in one sample JSON document. It cannot discover fields missing from the sample, API business rules, every possible union, framework conventions, or future schema changes, so review the result before production use.
