## 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 kale-x420-dev-4198b8b8 -d '<json body>'
```

Example prompt: Buy $20 worth of KALE tokens (contract 0x933C483A5d0Ac4234F4FA26b9950864Ca57afb07) using USDC and send them to my wallet.

## When to prefer this

Use this endpoint when an agent needs to programmatically purchase a specific custom dollar amount of KALE tokens using USDC, particularly in automated DeFi workflows or token accumulation strategies that require flexible spend amounts rather than fixed quantities.

## Known failure modes

- Insufficient USDC balance — payment rejected
- Invalid or zero USDC amount specified
- Token contract unavailable or liquidity too low — swap fails
- x402 payment header missing or malformed — 402 error returned
- Network congestion causing transaction timeout
- Slippage too high resulting in failed swap
