## 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-zero-knowledge-kyc-bridge-mcp-841335d5 -d '<json body>'
```

Example prompt: Run a zero-knowledge KYC check on this user's identity data — I need to verify compliance without exposing any raw personal information, and I want the transaction hash back as proof of the verification.

## When to prefer this

Choose this endpoint when you need privacy-preserving identity verification that produces an on-chain audit trail without exposing raw personal data. It is particularly suited for agent workflows that require KYC compliance gating with gasless USDC micropayments on Base L2. Prefer it over traditional KYC APIs when user data privacy and blockchain-verifiable attestation are both requirements.

## Known failure modes

- Invalid or malformed data string returns a processing error
- Insufficient USDC balance for the $0.25 per-call fee causes payment failure
- Network congestion on Base L2 may delay transaction confirmation
- Malformed JSON input schema causes a 400-level error
- ZK proof generation failure returns success: false with no txHash
