Same storage, sniffing and size rules as the avatar (avatar_service, slot launcher), and the same gate as the premium launcher styles: the studio lets anyone preview it and asks at Save, and this refuses a plan without premium_widget_design so the API cannot be used to skip that.

Path parameters#

Headers#

  • Idempotency-Keystring

    A unique key of your choosing, so this request can be retried safely. The first request with a given key executes; every replay returns that first response unchanged, with Idempotent-Replay: true set.

    Generate one key per action, not per session - reusing a key with a different body is refused with 422 rather than silently replaying the wrong answer. Keys are remembered for 24 hours. A request that failed releases its key, so a retry after fixing the payload runs normally.

  • 422Validation error

    The shared error envelope, served as application/problem+json with error.code set to validation_error. Its details name each field that failed and why.

Errors#

Failures use one envelope on every endpoint, described in Retries, versioning and limits. The codes you are most likely to meet here:

  • validation_error · 422 — The payload was well-formed JSON but failed schema validation.
  • unauthenticated · 401 — The request carried no API key, or one the API could not verify.
  • forbidden · 403 — The key is valid, but it is not allowed to do this — either the scope is missing or the resource belongs to another workspace.
  • idempotency_key_reused · 422 — This `Idempotency-Key` was used before, for a request with a different body.
  • rate_limited · 429 — Too many requests in the current window. The limit is per workspace, and some endpoints add a per-agent limit on top.
