# Versioning & support

> API versioning, schema stability, introspection, and how to get support.

Product: Clad API
Source: https://docs.useclad.ai/api/versioning

---

- This is **API v1**. `apiInfo` returns the current version and schema hash.
- The schema is additive-first: new fields and types may be added without
  notice; breaking changes are avoided within v1.
- Introspection is open to any valid credential, so the live schema in the API
  Explorer is always the current contract.
- For help, contact your Clad team and include the `requestId` (the
  `x-request-id` header) from the failing request.
