# M2MCent NLP Biometric Router MCP

> M2MCent NLP Biometric Router MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $1.452718/call, status unknown (last checked 2026-10-10).

Executes a natural language query against a monetized MCP node routing network, returning a boolean result via x402 micropayment settlement.

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-router-mcp-1238d4dc -d '<json body>'
```

Example prompt: Run this query through the M2MCent NLP biometric router and tell me the boolean result: 'Is the user identity verified for session 12345?'

## When to prefer this

Choose this endpoint when you need to route a natural language query to a specialized monetized MCP node and receive a simple boolean result, particularly in agent pipelines requiring a true/false gate settled via x402 USDC micropayments on Base L2. It is most useful when token context efficiency is critical and you need a lightweight binary decision from a remote AI node without embedding full LLM context.

## Known failure modes

- Payment failure — insufficient USDC balance causes x402 settlement to fail and the request is rejected
- Malformed query — missing or empty 'query' field returns a validation error
- Node unavailability — the targeted MCP subdomain node is offline or unresponsive
- Ambiguous query — the NLP router cannot determine a binary outcome and may return false by default
- Timeout — the remote MCP node does not respond within the expected window

## 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

A JSON object with a single 'result' field containing a boolean (true or false) indicating the outcome of the routed NLP query execution.
