Official SDK packages are not published yet. OpenAPI is available at /openapi/v1.json on the API host, and Scalar at /scalar/v1.
The repository generates TypeScript contracts with pnpm generate:api. The shared internal api-client is a foundation for a future hybrid SDK, not a published public package.
Use fetch or HttpClient today. Clients should handle Problem Details, Retry-After and cancellation. Do not automatically retry non-idempotent writes.
