# Robotics ZK Proof Router MCP

> Robotics ZK Proof Router MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.082156/call, status unknown (last checked 2026-10-11).

Accepts an audio input and returns a boolean ZK proof score, likely validating or verifying audio-based robotics data via a zero-knowledge proof routing mechanism.

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 robotics-zk-proof-router-mcp-c3602fe2 -d '<json body>'
```

Example prompt: Can you verify this audio recording through the robotics ZK proof router and tell me if it passes validation? Here's the audio data as a base64 string.

## When to prefer this

Use this endpoint when you need to cryptographically validate or verify audio data through a zero-knowledge proof mechanism in a robotics context, particularly when you need a simple pass/fail boolean result without exposing the underlying data.

## Known failure modes

- Missing required 'audio' field returns validation error
- Malformed or non-base64 audio string may cause processing failure
- Network timeout if audio payload is excessively large
- 402 Payment Required if USDC payment is not included or insufficient
- Invalid audio format not supported by the ZK router

## 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 field 'score' indicating whether the audio input passed ZK proof validation (true = valid/passes, false = invalid/fails).
