## 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 clash-of-coins-agentic-checkout-468c3068 -d '<json body>'
```

Example prompt: Go ahead and complete a purchase on Clash of Coins — submit a JSON checkout request and pay the $9 USDC fee to finalize the buy.

## When to prefer this

Choose this endpoint when you need an AI agent to autonomously complete a purchase on the Clash of Coins platform using the x402 crypto payment protocol with USDC. It is purpose-built for agentic (non-human) checkout flows where the $9 USDC fee is paid programmatically at call time. Prefer this over manual or browser-based checkout when automating game purchases or coin acquisitions in an agent pipeline.

## Known failure modes

- Payment of $9 USDC not included or insufficient — returns HTTP 402 requiring payment
- Malformed or missing required 'input' object in body — returns validation error
- Invalid bodyType enum value (not json, form-data, or text) — schema rejection
- Method not POST — endpoint rejects non-POST requests
- Network or settlement failure in x402 facilitator — transaction not confirmed
- Empty or invalid body field — checkout cannot be processed
