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 fintech-zk-proof-generator-mcp-node-421fc252 -d '<json body>'
```

Example prompt: Generate a zero-knowledge proof that a user's account balance is above $10,000 without revealing the actual balance amount.

## When to prefer this

Choose this endpoint when you need to generate privacy-preserving zero-knowledge proofs in a fintech context — particularly for compliance, balance attestation, or identity verification — and want a simple prompt-driven interface with pay-per-call USDC billing via x402 on Base L2.

## Known failure modes

- Invalid or malformed prompt input returns an error
- Proof generation failure returns hash: false
- Payment failure via x402 protocol blocks execution
- Timeout on complex proof computation
- Ambiguous prompt leading to incorrect proof parameters

## 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 containing a 'hash' field (boolean) indicating whether the zero-knowledge proof was successfully generated or verified. The boolean result confirms proof validity without exposing underlying data.
