## 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-biometric-extractor-mcp-node-m2mcent-106-4c2e9f81 -d '<json body>'
```

Example prompt: Extract any biometric information from this text: 'Subject has blue eyes, 6ft 2in height, distinctive scar on left cheek, and a resting heart rate of 62 bpm.'

## When to prefer this

Use this endpoint when you need to extract biometric attributes or identifiers from unstructured natural language text as part of an automated pipeline, particularly when operating within the M2MCent MCP node network with x402 micropayment settlement on Base L2.

## Known failure modes

- Missing required 'data' field returns validation error
- Empty string input may return false boolean
- Malformed JSON body causes 400-level error
- Service unavailability or payment failure (402) if USDC balance insufficient
- Ambiguous or non-biometric text may yield false negative

## 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 containing a boolean value indicating whether the extraction processed successfully or matched a biometric URL reference in the input text. The schema is minimal and the boolean likely signals presence/absence or success/failure of the biometric extraction operation.
