## 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 catc-x420-dev-7b5148f1 -d '<json body>'
```

Example prompt: Buy me 10 USDC worth of CATC tokens right now.

## When to prefer this

Use this endpoint when you need to purchase a specific custom USDC amount of CATC tokens rather than a fixed 1 USDC increment. Prefer this over the fixed sibling endpoint when the user specifies any amount other than exactly 1 USDC (e.g. 0.5, 10, 50 USDC).

## Known failure modes

- Invalid or non-numeric USDC amount string returns error
- Insufficient USDC balance or approval causes transaction failure
- On-chain swap slippage or liquidity issues may cause swap transaction hash to be null
- Network congestion on Base chain may delay or fail the transaction
- Amount below minimum threshold (e.g. 0 or negative) rejected
