## 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 x402-clashofcoins-com-1c240497 -d '<json body>'
```

Example prompt: I want to buy an item from the Clash of Coins shop — process a POST purchase for the standard item type and complete the checkout using my wallet.

## When to prefer this

Use this endpoint when an AI agent needs to make an automated in-game purchase in Clash of Coins using the x402 micropayment protocol with USDC. It is the dedicated agentic checkout path, distinct from the wallet funding route or the health probe endpoint on the same domain.

- Item unavailable or out of stock – 404 or 422 response
