Request

  • Base URL: https://api.app.layer.ai/api
  • URL: https://api.app.layer.ai/api/v1/workspaces/{workspace_id}/training-runs

    • HTTP bearer

Path parameters

workspace_idstring uuid required

Id of the workspace that owns the resource.

Headers

Idempotency-Keystring

Opaque key making a retry of this request return the first result. A 2xx response is replayed for 24 hours with Idempotent-Replayed: true. A 4xx releases the key. A 5xx, or a request still running, holds the key for 120 seconds, during which a retry gets 409; after that a retry executes again. The key covers the method, path, query, and byte-identical body it was first used with; reusing it for a different request is rejected with 422. Protection is best effort: if the key store is unavailable, or a record is lost early, a retry can execute again even after an earlier 409. See the Idempotency section of the API description.
