Flux Image Generation API

Get your Ace Data Cloud API key

Open Ace Data Cloud → Applications. Sign in, or register an account first.
Find General application. If it has not been created, choose Initialize General Application. A general key can use the services available to your account; a dedicated application's key is limited to its service. Check the required service/model access and current pricing.
Copy the API Key from the application card, or open Keys / Manage Keys → Create to create a separate key for this integration. Give it a recognizable name so you can revoke or rotate it independently.
When creating a key, review Expiration Time, Set Usage Limitation, and Allowed APIs. Enable only the restrictions you need, allow the operations you will call, then click Create and copy the token from the key list. Task lookup does not grant permission to submit a generation. Confirm the application's balance can cover your first request; any trial allowance is whatever your account currently displays.
Copy only the token value, without quotation marks, spaces, or Bearer . An API Key / API Token field expects this raw value; only a manually configured HTTP Authorization header needs the Bearer prefix. A platform-... account-management token cannot replace a generation API key.

Save the key in the client's credential store or the environment variable shown below. Never put it in a prompt, shared workflow, screenshot, or Git commit. If authentication fails, check the full copied value, application/service access, expiration, usage limit, and balance before creating another key.

FLUX 3 video generation

POST /flux/videos now supports action="generate" with mode set to t2v, i2v, v2v, or draft_enhance. Use async=true, retain the returned task ID, and poll /flux/tasks. Video editing and upscaling are not published.

Normal generation accepts model="flux-3", prompt, duration, resolution, draft, and generate_audio; preserve explicit false. I2V additionally needs keyframes, V2V needs start_video, and draft enhancement needs an owned draft_task_id. See the current video guide for mode-specific limits and examples.
