## 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 box-mysterious-box-mint-1-box-aeaa8a2b -d '<json body>'
```

Example prompt: Mint 1 BOX mystery box for my wallet address 0xAbC123...def and pay with 1 USDC.

## When to prefer this

Use this endpoint when a user wants to mint exactly one BOX mystery box NFT on the Base network using USDC via the x402 micropayment protocol. Prefer this over the sibling 'open 6 mystery boxes' endpoint when the user wants to acquire (mint) a single box rather than open/reveal existing boxes.

## Known failure modes

- Insufficient USDC balance — payment fails, box not minted
- Invalid or malformed buyer wallet address — request rejected
- USDC payment not approved or allowance too low — transaction reverts
- Network congestion on Base — timeout or delayed confirmation
- Invalid token symbol provided — request error
- Amount string malformed or mismatched tier — rejected
