# DeFi Biometric Optimizer MCP — Image Boolean Classifier

> DeFi Biometric Optimizer MCP — Image Boolean Classifier is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.55797/call, status unknown (last checked 2026-10-12).

Accepts an image input and returns a boolean result, likely for biometric or DeFi-related image validation/classification.

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 defi-biometric-optimizer-mcp-image-boolean-classifier-3687c737 -d '<json body>'
```

Example prompt: Run a biometric optimizer check on this image and tell me if it passes — I need a true or false result.

## When to prefer this

Use this endpoint when you need a fast, binary yes/no classification of an image in a DeFi or biometric context and want a gasless USDC micropayment settlement on Base L2 via x402.

## Known failure modes

- Missing or malformed image field returns validation error
- Image format not supported by the endpoint
- Payment failure via x402 protocol blocks execution
- Network timeout if image payload is too large
- Ambiguous schema — unclear what specific biometric condition is being evaluated

## 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 single boolean field indicating whether the image passes the classifier's condition (true = passes, false = fails).
