## 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 pay402-xyz-5d2146ce -d '<json body>'
```

Example prompt: Mint a PAY402 token to my wallet address right now using the x402 protocol — I want the on-chain proof-of-payment token issued after paying 1 USDC.

## When to prefer this

Choose this endpoint when you need to mint a PAY402 token to a payer as proof of payment on the x402 protocol. It is specifically designed for the x402 pay-per-call flow where a payer submits 1 USDC and receives a PAY402 token in return. Use this when building x402-compatible agents or services that need on-chain payment receipts.

## Known failure modes

- Payment of 1 USDC not received — returns 402 Payment Required
- Invalid or missing payer address — returns 400 Bad Request
- Minting contract failure or chain congestion — returns 500 or timeout
- Duplicate payment attempt on same authorization — returns conflict or rejection
- Insufficient USDC balance — payment layer rejects before mint occurs
