# Robotics ZK Proof Optimizer

> Robotics ZK Proof Optimizer is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.641698/call, status unknown (last checked 2026-10-10).

Takes an audio input and returns a boolean prediction, ostensibly related to robotics zero-knowledge proof optimization via an MCP node.

## Facts

- Endpoint: POST https://api.m2mcent.com/robotics-zk-proof-optimizer-mcp-988/api/execute?utm_source=zero.xyz
- Price: $0.641698/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-10
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/robotics-zk-proof-optimizer-6bfd6ae1

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-optimizer-6bfd6ae1 -d '<json body>'
```

Example prompt: Run this audio file through the robotics ZK proof optimizer and tell me whether it returns a true or false prediction.

## When to prefer this

Use this endpoint when you need a simple boolean classification of audio input within a robotics or ZK proof pipeline, and you are already operating within the x402/USDC micropayment infrastructure on Base L2.

## Known failure modes

- Missing 'audio' field in request body returns validation error
- Invalid or malformed audio string causes processing failure
- Payment not fulfilled via x402 protocol results in 402 response
- Network or node availability issues on the MCP node
- Ambiguous audio encoding may yield unpredictable predictions

## 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 'prediction', indicating whether the audio input satisfies the zero-knowledge proof optimization criteria for the robotics use case.
