Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-c86e0c95 -d '<json body>'
```

Example prompt: Use Seedance 2 Pro to generate a 10-second 16:9 cinematic video of a bustling Tokyo street at night with neon lights reflecting off wet pavement, output at 1080p.

## When to prefer this

Choose this endpoint when you need high-quality AI text-to-video generation using the Seedance 2 Pro model specifically, especially when you want control over duration (4–15 seconds), aspect ratio, resolution tier (480p–1080p), or optional 4K upscaling. Prefer this over image-to-video (I2v) when you have no source image. Prefer over Sora or Veo endpoints if Seedance's visual style is desired or if cost/availability differs.

## Known failure modes

- Invalid or missing prompt returns 400 validation error
- Unsupported duration value outside enum returns validation error
- Unsupported resolution or aspect ratio combination returns 400
- Payment failure (insufficient USDC balance) returns 402
- Job creation failure returns non-success response
- Callback URL malformed returns 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 jobId string for polling the job status, status='pending', and a type string ('seedance-t2v'). The agent must poll a separate endpoint using the jobId to retrieve the final video once rendering completes.
