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 m2mcent-nlp-biometric-aggregator-mcp-node-6063a42a -d '<json body>'
```

Example prompt: Run the NLP biometric aggregator on this dataset string and give me back the summary result.

## When to prefer this

Choose this endpoint when you need to run NLP biometric aggregation on a string dataset and only require a boolean summary output, particularly within a monetized MCP node workflow using x402 USDC payments on Base L2.

## Known failure modes

- Missing 'dataset' field returns validation error
- Malformed dataset string may cause processing failure
- Payment failure via x402 protocol prevents execution
- Timeout if dataset is too large or node is unavailable
- Boolean summary may be ambiguous without additional context fields

## 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 a 'summary' boolean field indicating the aggregated NLP biometric result for the submitted dataset.
