## 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-generate-66726256 -d '<json body>'
```

Example prompt: Generate a 6-second 1080p landscape video of a bustling Tokyo street at night with neon lights reflecting off wet pavement, cinematic atmosphere — use Veo 3.1 and avoid any blurry or overexposed shots.

## When to prefer this

Choose this endpoint when you need high-quality AI video generation powered by Google's Veo 3.1 model specifically, especially when you want support for first-frame image conditioning, last-frame interpolation, or reference-image style guidance alongside a text prompt. Prefer this over other StableStudio video endpoints (Seedance, Wan) when Veo 3.1 quality or Google's video model characteristics are desired.

## Known failure modes

- Missing required 'prompt' field returns a 400 validation error
- Invalid image URL format for 'image' or 'lastFrame' fields causes a 422 error
- Unsupported enum value for resolution, aspectRatio, durationSeconds, or imageMode returns a validation error
- Payment failure or insufficient USDC balance returns a 402 Payment Required
- Service unavailability or model overload may return a 503 error
- Prompt violates content policy and is rejected with a 400 or 403 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, status='pending', and type='veo-3.1-video'. The job ID must be polled separately to retrieve the completed video URL once rendering is done.

 "prompt": "A serene landscape showing a calm lake at sunset with mountains in the background, golden hour lighting, peaceful and tranquil atmosphere",
 "resolution": "720p",
