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 iot-voice-synthesis-auditor-mcp-node-255e1d15 -d '<json body>'
```

Example prompt: Can you audit this IoT voice synthesis dataset for me — here's the dataset string — and let me know if it passes validation?

## When to prefer this

Choose this endpoint when you need a focused, low-cost automated audit specifically for IoT-sourced voice synthesis datasets and only require a boolean pass/fail result. It is best suited for lightweight validation gates in IoT speech pipelines where a simple status verdict is sufficient and token efficiency matters.

## Known failure modes

- Missing 'dataset' field returns a 400 validation error
- Malformed or empty dataset string may return false status or an error
- Payment failure via x402 protocol results in 402 response and no audit result
- Network timeout if dataset is too large or node is unavailable
- Node-specific downtime on this subdomain may cause 503 errors

## 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 boolean 'status' field indicating whether the submitted dataset passed the IoT voice synthesis audit (true = passed, false = failed).
