## 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 lfg-token-purchase-1-usdc-x420-dev-a1961087
```

Example prompt: Buy 1 USDC worth of LFG tokens for me right now using the x420 LFG API and tell me how many tokens I received and the transaction hashes.

## When to prefer this

Use this endpoint when you want to buy exactly 1 USDC worth of LFG tokens programmatically via the x402 payment protocol. Prefer the sibling 5 USDC endpoint if you want a larger purchase in a single call. This is the minimum denomination available on x420.dev for LFG token acquisition.

## Known failure modes

- Insufficient USDC balance — payment rejected
- x402 payment protocol failure — 402 Payment Required returned
- Token contract unavailable or liquidity too low — swap fails
- Network congestion causing transaction timeout — null transaction hashes returned
- Invalid payment credentials — authorization error
