## 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 nlp-voice-synthesis-auditor-mcp-45ff9e6d -d '<json body>'
```

Example prompt: Can you audit this NLP voice synthesis dataset and tell me whether it passes validation? Here's the dataset: 'base64_encoded_audio_sample_xyz'.

## When to prefer this

Use this endpoint when you need a lightweight, binary pass/fail audit of a voice synthesis or NLP audio dataset, especially in automated pipelines where a simple boolean prediction is sufficient and cost-per-call matters.

## Known failure modes

- Missing or empty 'dataset' field returns a validation error
- Malformed or oversized dataset string may cause processing failure
- Payment failure via x402 protocol results in 402 response and no prediction
- Ambiguous or unsupported dataset format may yield unreliable boolean output

## 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 single boolean 'prediction' field — true if the dataset passes the NLP voice synthesis audit, false if it fails.
