# ZK Proof Generator MCP

> ZK Proof Generator MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.75/call, status unknown (last checked 2026-10-17).

Generates a zero-knowledge proof for a given computation, returning a boolean proof result

## Facts

- Endpoint: POST https://api.m2mcent.com/zk-proof-generator-mcp/api/prove?utm_source=zero.xyz
- Price: $0.75/call
- Payment: x402

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 zk-proof-generator-mcp-e6a0ccf3 -d '<json body>'
```

Example prompt: Can you generate a zero-knowledge proof for this computation: 'x = 5 satisfies x^2 = 25' — I need a boolean proof result I can use to verify it without revealing the inputs.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-use ZK proof generation service accessible via HTTP with USDC micropayments, especially when integrating with Base L2 workflows or needing gasless settlement. Prefer this over self-hosted ZK prover infrastructure when cost efficiency and simplicity matter more than full circuit customization.

## Known failure modes

- Invalid or unparseable computation string returns an error
- Malformed computation syntax may produce unexpected false proofs
- Payment failure via x402 protocol results in 402 response before proof is generated
- Computation too complex or unsupported format returns an error
- Network timeout for computationally intensive proofs

## 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 'proof' indicating whether the zero-knowledge proof for the provided computation is valid (true) or invalid (false).
