API reference

Every client.<namespace> maps to a resource class, grouped below by area. Each method page lists arguments, return type, and the typed errors it raises (with stable ErrorCodes) — generated from the code, so it never drifts.

• Client — construction, config, env vars.
• Datasets & assets, Projects & ontology, Labeling workflow, Annotations, Versions & exports, Training & serving, Inference, Curation & activity, Identity & access, Jobs.
• Types & errors — request TypedDicts and the exception taxonomy.
