## 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 gunlet-gun-token-purchase-1-usdc-041d841c
```

Example prompt: Buy me 1 USDC worth of GUN tokens using the GUNLET service on x420.dev — I want to receive the GUN tokens at contract 0x813E69a5D2fAb3D9510Ab9DC35151aB4dA9E7B07 and confirm the swap transaction hash.

## When to prefer this

Use this endpoint when you need to programmatically acquire a small amount of GUN tokens (exactly 1 USDC worth) in a single API call with x402 micropayment support. Prefer this over the 5 USDC variant when you want a smaller, lower-risk purchase or when testing the integration.

## Known failure modes

- Insufficient USDC balance — payment fails with 402 or rejection
- x402 payment header missing or malformed — request rejected before execution
- On-chain swap fails — swapTransactionHash may be null and message indicates failure
- Token contract unavailable or liquidity insufficient — swap cannot complete
- Network congestion causes timeout before transaction confirms
