## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability stablestudio-t2v-8757f016 -d '<json body>'
```

Example prompt: Use Seedance Fast to generate a 10-second 16:9 video of a red fox trotting through a snowy pine forest at dusk, soft warm lighting, cinematic style — output at 720p.

## When to prefer this

Choose this endpoint when you need fast AI-generated video from a text description and are willing to pay per generation. Prefer this over Seedance 2 Pro when speed is prioritized over maximum quality. Use this over image-generation endpoints when the output must be a video clip. Ideal for short-form content creation (4–15 seconds) at 720p quality.

## Known failure modes

- Missing or empty prompt returns 400 validation error
- Invalid duration value outside allowed enum returns 400
- Invalid aspect ratio or resolution combination returns 400
- Payment of $20 USDC not included or insufficient returns 402
- Job creation fails server-side returning 500 with no jobId
- Callback URL malformed returns 400 URI validation error

## How this service works

Pay-per-generation AI image and video creation. No subscriptions ever.

## Output

Returns a JSON object with success=true, a unique jobId string, status='pending', and type='seedance-fast-t2v'. The agent must poll or use a callback URL to retrieve the final video once the async job completes.
