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-web3-zk-proof-generator-mcp-node-b57a94fe -d '<json body>'
```

Example prompt: Generate a zero-knowledge proof for the following statement: 'I am over 18 years old without revealing my birthdate' using the M2MCent ZK proof generator MCP node.

## When to prefer this

Choose this endpoint when you need to generate zero-knowledge proofs programmatically via a monetized remote MCP node with gasless USDC settlement on Base L2. Suitable for agents needing cryptographic proof generation without managing on-chain gas fees directly.

## Known failure modes

- Missing required 'prompt' field returns a validation error
- Insufficient USDC balance causes payment failure via x402 protocol
- Ambiguous or malformed prompt may result in status: false
- Network or node unavailability on Base L2 may cause timeout
- ZK proof computation failure for unsupported proof types returns false status

## 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 boolean 'status' field indicating whether the ZK proof generation task executed successfully or not.
