## 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 m2mcent-metaverse-voice-synthesis-mcp-node-5206166e -d '<json body>'
```

Example prompt: Can you synthesize a voice from this image I have — here's the image data — and give me back a URL to the audio?

## When to prefer this

Use this endpoint when you need to synthesize voice audio from an image input within a monetized MCP/x402 payment flow on Base L2, particularly in metaverse or avatar-driven contexts where USDC micropayments are acceptable.

## Known failure modes

- Missing or invalid 'image' field returns a 400 error
- Payment failure via x402 protocol results in 402 Payment Required
- Malformed image data may result in synthesis failure
- Server-side synthesis errors return 500
- Schema inconsistency: response 'url' typed as boolean may indicate unstable or stub API

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a JSON object with a 'url' field (typed as boolean in schema, likely a URL string in practice) pointing to the generated voice audio output.
