## 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-open-6-mystery-boxes-a8e257cd -d '<json body>'
```

Example prompt: Open 6 mystery boxes from $BOX Mysterious Box for my wallet address 0xAbC1234567890abcdef1234567890abcdef123456, paying the $5 USDC tier.

## When to prefer this

Use this endpoint when a user wants to open 6 mystery boxes in a single call at the $5 USDC price point on the Base network, as opposed to the sibling endpoint which mints a single BOX for a lower tier.

## Known failure modes

- Payment not received or insufficient USDC — returns error or no success flag
- Invalid or missing buyer wallet address — request rejected
- Incorrect USDC tier amount string — may cause processing failure
- Network or settlement delay causing tx_hash mismatch
- Service downtime on api.402xmysterious.fun returning 5xx errors
