## 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-analyzer-mcp-node-0d2a70ae -d '<json body>'
```

Example prompt: Can you run this audio through the NLP yield analyzer and tell me whether it passes or not?

## When to prefer this

Use this endpoint when you need a simple boolean yield determination from audio input and are operating in an x402-enabled payment environment on Base L2. Suited for agents that require lightweight, low-context audio classification with gasless USDC micropayments.

## Known failure modes

- Missing 'audio' field in request body returns a validation error
- Payment not processed (x402 USDC settlement failure) results in 402 response
- Malformed or unsupported audio string format may cause processing errors
- Server-side analysis failure may return a 500 error with no result
- Network timeout on the remote MCP node returns no response

## 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 containing an 'analysis' boolean field — true or false — indicating whether the submitted audio passed the yield analysis criteria.
