## 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 x105-x420-dev-2c0a6e6b -d '<json body>'
```

Example prompt: Buy me $25 worth of x105 tokens using USDC — use the custom amount option so I can specify exactly 25 USDC.

## When to prefer this

Use this endpoint when you need to purchase a specific non-default USDC amount of x105 tokens rather than the fixed $5 default. Ideal when the user wants to specify exactly how much USDC to spend (e.g., $10, $0.50, $100) on x105 tokens in a single agentic payment call.

## Known failure modes

- Insufficient USDC balance results in payment failure
- Invalid or non-numeric amount string causes request error
- Amount below minimum threshold may be rejected
- On-chain swap failure returns null swap transaction hash with error message
- Network congestion may delay transaction confirmation
