## 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 treasure-trio-item-pack-coins-x500-db83d1a8
```

Example prompt: Buy me the Treasure Trio item pack — I want the 500-coin bundle for 1 USDC on Base so I can keep playing.

## When to prefer this

Use this endpoint specifically when a user wants to purchase the 500-coin non-withdrawable item pack for the Treasure Trio game on the scdoscan.io platform and is willing to pay 1 USDC on Base via the x402 protocol. Prefer this over sibling tip endpoints when the goal is to receive in-game coins rather than send a gratuity, and prefer it over item packs for other games (e.g. Kitten Boarding Party) when the user is playing Treasure Trio specifically.

## Known failure modes

- Insufficient USDC balance on Base — payment rejected
- x402 payment protocol failure — transaction not confirmed
- Network or gateway error returning a non-2xx HTTP response
- Invalid or missing required input fields (type or method) causing a 400 error
- Duplicate request causing idempotency issues — coins may not be double-credited
