## 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 video-dubbing-api-x402-83e5beba -d '<json body>'
```

Example prompt: Can you dub this video into Spanish for me? Here's the video link: https://example.com/myvideo.mp4 — I need the audio replaced with a natural-sounding Spanish voice that stays in sync with the original speech.

## When to prefer this

Choose this endpoint when you need to replace or overlay a video's audio track with AI-generated speech in a different language, particularly in an automated agent workflow that supports x402 micropayment authentication. It is well-suited for content localization pipelines, multilingual publishing workflows, or any scenario where generating a dubbed video programmatically at $0.30 per call is cost-effective compared to manual dubbing services.

## Known failure modes

- Invalid or inaccessible video URL returns an error status
- Unsupported target language results in a bad request error
- Video file too large or too long may cause timeout or rejection
- Malformed input object missing required fields returns validation error
- Payment failure via x402 protocol blocks request processing
- Network latency or processing delays may cause slow or failed responses

## How this service works

Agent-ready x402 APIs for AI video production, audio localization, web research, document extraction, data analysis, and structured JSON transformation.

## Output

Returns a JSON object containing a status string, a unique request_id for tracking, and a result object that typically includes a URL or data for the dubbed video with localized audio synchronized to the original video timing. May also include usage metadata, model_used, warnings, and payment confirmation details.
