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 m2mcent-legal-tech-voice-synthesis-aggregator-mcp-391bfe1f -d '<json body>'
```

Example prompt: Please synthesize this legal clause into spoken audio: 'The party of the first part agrees to indemnify and hold harmless the party of the second part from any and all claims arising from the use of the licensed materials.'

## When to prefer this

Choose this endpoint when you need legal-domain text-to-speech synthesis via an x402-monetized MCP node with USDC micropayment settlement on Base L2, particularly when integrating with other MCP-compatible legal tech tooling or when low per-call cost and gasless settlement are priorities.

## Known failure modes

- Missing or empty 'text' field returns a validation error
- Very long text inputs may exceed processing limits or time out
- Malformed request body returns 400-level error
- Payment failure via x402 protocol results in 402 Payment Required response
- Audio generation service unavailable returns 5xx error
- Schema inconsistency: 'url' field typed as boolean may cause parsing issues

## 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 audio file of the synthesized speech.
