## 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 munch-x420-dev-c4657d6b -d '<json body>'
```

Example prompt: Buy $50 worth of MUNCH tokens (contract 0x70B1dC3d736F164befCb23388608DD822b253B07) using USDC for my wallet.

## When to prefer this

Use this endpoint when an agent needs to programmatically purchase a precise dollar-denominated USDC amount of MUNCH tokens in a single API call, especially when operating in an x402 payment-enabled agentic workflow where the $5 USDC service fee can be paid automatically.

## Known failure modes

- Insufficient USDC balance to cover purchase amount plus $5 API fee
- Invalid or missing USDC amount in request body
- Token contract unavailable or liquidity too low for the requested swap
- Network congestion causing transaction failure or timeout
- Malformed request resulting in 400 Bad Request
- x402 payment header missing or invalid resulting in 402 Payment Required
