## 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-sora-2-pro-video-generation-3c59dae8 -d '<json body>'
```

Example prompt: Use StableStudio to generate a Sora 2 Pro video of a lone astronaut walking across a red desert at sunset, in 16:9 aspect ratio at 2 MP resolution, output as webp with quality 90 and safety tolerance set to 2.

## When to prefer this

Choose this endpoint when you need to generate AI video using OpenAI's Sora 2 Pro model on a pay-per-call basis with no subscription required. Prefer it over subscription-based video generation services when cost-per-call billing fits the use case, or when the agent needs to use Sora 2 Pro specifically. Use when the output is a video (not a static image) and when async job-based delivery is acceptable.

## Known failure modes

- Invalid or missing prompt returns 400 validation error
- Resolution or aspect_ratio value outside allowed enum fails with 422
- Payment not completed (x402 flow not fulfilled) results in 402 Payment Required
- Safety tolerance out of range (below 1 or above 5) causes rejection
- Sora 2 Pro model backend unavailable returns 503 or timeout
- Prompt exceeds 10,000 character limit returns 400

## How this service works

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

## Output

A JSON object containing a jobId string (e.g. 'cmpbmzaee000j04jrzx4f43tw'), a status field (e.g. 'pending'), a type field ('sora-2-pro-video'), and a success boolean. The agent should poll or retrieve the job result separately using the jobId.
