## 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 x420bot-x420-dev-5911ff92 -d '<json body>'
```

Example prompt: Buy me $15 worth of X420Bot tokens using USDC — use the custom amount endpoint so I get exactly 15 USDC worth.

## When to prefer this

Use this endpoint when you want to purchase a specific, non-default USDC amount of X420Bot tokens programmatically; prefer over the fixed-price endpoint when you need flexibility in spend amount (e.g. 0.5, 10.5, or any custom value rather than the default 5 USDC).

## Known failure modes

- Insufficient USDC balance results in failed transaction
- Invalid or non-numeric amount string causes bad request error
- Network congestion may delay or fail the swap transaction
- Amount below minimum threshold may be rejected
- Swap transaction hash may be null if swap step fails mid-execution
