# Cybersecurity ZK Proof Extractor MCP

> Cybersecurity ZK Proof Extractor MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.170483/call, status unknown (last checked 2026-10-11).

Accepts audio input and returns a boolean result indicating whether a zero-knowledge proof is detected or validated within the cybersecurity context

## 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 cybersecurity-zk-proof-extractor-mcp-9d9a91ad -d '<json body>'
```

Example prompt: Check this audio file for a valid zero-knowledge proof and tell me if it passes — here's the audio data as a base64 string.

## When to prefer this

Choose this endpoint when you need to detect or validate zero-knowledge proofs embedded within audio data in a cybersecurity context. It is purpose-built for ZK proof extraction from audio signals, unlike general-purpose audio analysis or text-based ZK proof validators.

## Known failure modes

- Missing or malformed 'audio' field returns a validation error
- Non-base64 or unsupported audio encoding may cause parsing failure
- Audio with no detectable ZK proof returns result: false
- Network timeout or payment failure via x402 protocol blocks execution
- Malformed audio string that cannot be decoded returns an error response

## 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 'result' field: true if a zero-knowledge proof is successfully extracted or validated from the provided audio, false otherwise.
