# M2MCent Metaverse ZK Proof Classifier MCP

> M2MCent Metaverse ZK Proof Classifier MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.584295/call, status unknown (last checked 2026-10-11).

Executes a metaverse zero-knowledge proof classification task via a monetized remote MCP node, returning a URL result.

## Facts

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-metaverse-zk-proof-classifier-mcp-9011c4be -d '<json body>'
```

Example prompt: Classify this ZK proof payload from my metaverse session and tell me if it passes verification: 'eyJhbGciOiJaS1Byb29mIn0...'

## When to prefer this

Choose this endpoint when you need to classify or validate zero-knowledge proofs specifically in a metaverse context and are comfortable paying per-call via USDC x402 on Base L2. This is appropriate if you need a remote MCP node execution model with gasless settlements.

## Known failure modes

- Missing or malformed payload string returns a validation error
- Invalid ZK proof format may result in classification failure or unexpected boolean result
- Payment failure via x402 protocol prevents execution
- Endpoint may return unexpected schema (boolean where URL string expected) due to schema inconsistency
- Network timeouts on the Base L2 settlement layer

## 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 (boolean) indicating the outcome of the ZK proof classification. The boolean value signals whether the proof passes or fails the classifier's criteria.
