## 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-mcp-72591ea5 -d '<json body>'
```

Example prompt: Can you run a zero-knowledge KYC check on this user data string and tell me if it passes verification — I need the result and the on-chain transaction hash.

## When to prefer this

Choose this endpoint when you need privacy-preserving, on-chain KYC verification that produces a verifiable transaction hash without exposing raw user data — particularly when operating in a Web3 context requiring Base L2 attestations and gasless USDC payments via x402 protocol.

## Known failure modes

- Invalid or malformed data string returns an error or false success flag
- Payment failure (insufficient USDC) prevents processing
- On-chain settlement failure on Base L2 may cause missing or null txHash
- Empty or missing 'data' field in request body causes validation error
- Network timeout on MCP node may return no response

## 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 transaction hash (e.g. '0xMockTransactionHash...') and a boolean success field indicating whether the zero-knowledge KYC verification was processed and attested on-chain.
