api

• REST API

  Classic Semitexa REST endpoints with typed payloads, versioning, and consumer-friendly response shaping.

• Structured Errors

  Throw domain exceptions and let semitexa-api map them into stable machine-readable error envelopes.

• Active Version

  The current collection endpoint with a clean X-Api-Version header and no deprecation noise.

• Sunset Version

  A deprecated product endpoint that emits both Deprecation and Sunset headers.

• Schema Discovery

  A mini Swagger-style explorer for the live product API contract, schema endpoint, and response shapes.

• GraphQL API

  GraphQL-first Semitexa contracts built with typed payloads and typed output DTOs instead of resolver sprawl.

• REST + GraphQL

  One Semitexa use case can serve both REST and GraphQL without duplicating handler logic into separate resolver classes.
