# M2MCent Metaverse ZK Proof Auditor MCP

> M2MCent Metaverse ZK Proof Auditor MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.33728/call, status unknown (last checked 2026-10-11).

Accepts an audio input and returns a boolean status result, ostensibly as a metaverse zero-knowledge proof auditing service via a monetized MCP node.

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-auditor-mcp-9901b4a7 -d '<json body>'
```

Example prompt: Can you run this audio file through the metaverse ZK proof auditor and tell me whether the proof is valid?

## When to prefer this

Use this endpoint when you specifically need to validate or audit a zero-knowledge proof delivered as audio data in a metaverse context, and require a simple boolean pass/fail result via a monetized MCP node on Base L2.

## Known failure modes

- Missing or malformed 'audio' field returns an error
- Invalid audio encoding causes processing failure
- Payment failure (x402) results in 402 response before execution
- Service unavailability returns 5xx error
- Ambiguous status result with no error detail

## 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 single boolean 'status' field indicating whether the submitted audio input passed or failed the ZK proof audit check.
