## 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-nlp-yield-validator-mcp-node-260-d8349b83 -d '<json body>'
```

Example prompt: Can you validate this audio sample against the NLP yield validator and tell me whether it passes or fails?

## When to prefer this

Use this endpoint when you need a simple boolean pass/fail NLP yield validation on an audio input and are operating within the x402 micropayment ecosystem on Base L2. Appropriate for automated pipelines needing lightweight audio quality gating without complex analysis output.

## Known failure modes

- Missing 'audio' field in request body returns validation error
- Invalid or non-string audio value may cause processing failure
- Payment failure or insufficient USDC balance blocks execution
- Malformed audio data may yield false negatives
- Network timeout on large audio payloads
