## 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 audio-watermarking-detector-mcp-b41a01b6 -d '<json body>'
```

Example prompt: Can you check this audio clip for any embedded watermarks — I want to know if it's been watermarked, like by an AI audio generator?

## When to prefer this

Choose this endpoint when you need to programmatically verify whether an audio file or stream has been watermarked — especially for detecting AI-generated content watermarks, verifying content authenticity, or building automated content moderation pipelines. It is well-suited for agentic workflows that require fast, per-file watermark verification.

## Known failure modes

- Invalid or malformed audio data string returns an error
- Audio format not supported may yield no detection result
- Very short audio clips may be insufficient for reliable detection
- Network timeout for large audio payloads
- Payment not processed results in 402 response
