How Generation Calls Work

Every generation tool is synchronous: the call blocks until the asset is ready and returns the result (with its URLs) directly in the response. There is no separate polling step, and dropping the connection before the call returns cancels the request. Long-running operations such as 3D models and animations can take 30–120 seconds, so allow a generous client-side timeout.

Retrieving Results Later

Every generation tool also accepts an optional request_id. This does not make the call asynchronous — it tags the result so you can fetch it again afterwards from the matching results endpoint (for example from a different session, or to list everything tied to one request). The result is persisted only after the synchronous call has completed successfully.

# Generate a sprite animation — this call blocks and returns the spritesheet directly
animateSprite with request_id="my-anim-001", initial_image="url", motion_prompt="walking"

# Later, re-fetch that same result (e.g. in another session) by its request_id
getSpriteResults with request_id="my-anim-001"

Results are available for 7 days, and each results endpoint is free and returns up to 100 recent API-generated assets.

---

Asset URL Expiration

All generated asset URLs (images, spritesheets, videos, audio, 3D models) are temporary and expire after 7 days. If you need to keep an asset, download it before it expires.
