# M2MCent Supply Chain Biometric Classifier MCP

> M2MCent Supply Chain Biometric Classifier MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.928989/call, status unknown (last checked 2026-10-10).

Classifies supply chain biometric data via a monetized remote MCP node using the x402 payment protocol on Base L2.

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-supply-chain-biometric-classifier-mcp-494eafbb -d '<json body>'
```

Example prompt: Classify this supply chain biometric record and tell me whether it passes: here is the raw data string from the warehouse access log.

## When to prefer this

Choose this endpoint when you need automated biometric classification specifically within a supply chain or logistics context and are operating in an x402-enabled agent environment that can handle USDC micropayments on Base L2. It is appropriate when you need a simple pass/fail classification signal rather than rich scoring or multi-factor identity data.

## Known failure modes

- Missing or malformed 'data' field returns a 400-level error
- Invalid or non-biometric string may return status: false without explanation
- Payment failure via x402 results in a 402 response and no classification
- Network timeout on the remote MCP node returns no status
- Oversized data payload may be rejected silently or with a 413 error

## 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 boolean 'status' field indicating whether the biometric classification passed (true) or failed (false).
