API Reference

Complete API documentation for all SLC endpoints.

API Versioning

SLC uses versioned API endpoints to ensure backward compatibility and smooth migrations. All public API endpoints support versioning through the `/v1/` namespace.

Default: If not specified, the CLI defaults to `v1`.

All versioned endpoints follow the pattern: /{version}/{endpoint}
