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 hypercli-speaking-video-generation-25175470 -d '<json body>'
```

Example prompt: Using HyperCLI, generate a speaking video where the person in this portrait photo (https://example.com/portrait.jpg) talks along with this voiceover audio (https://example.com/speech.mp3) — use the prompt 'professional business presentation' and render it at 512x512.

## When to prefer this

Use this endpoint when you need to animate a static image or portrait to sync with audio, creating a talking-head or lip-sync video. Ideal for AI avatar creation, video presentations, or any use case combining a still image with spoken audio into a dynamic video. Prefer over text-to-video when you already have a specific image and audio track to combine.

## Known failure modes

- Invalid or inaccessible image_url returns an error or failed render
- Invalid or inaccessible audio_url causes audio processing failure
- Unsupported width/height dimensions may cause rendering errors
- Missing required prompt field results in a validation error
- Payment failure via x402 protocol prevents job creation
- Async job timeout if render takes too long on the backend

## How this service works

speaking-video — fixed price $0.25

## Output

Returns a JSON object with an access key to retrieve the rendered video, a status URL to poll for job completion, a cancel URL to abort the job, and a render object with job details. The video is generated asynchronously and can be monitored via the status URL.
