## 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-5-usdc-via-x420-dev-3bc0b1ff
```

Example prompt: Buy me $5 worth of GUN tokens using x420.dev's GUNLET service — execute the swap now and let me know how many GUN tokens I received and the transaction hashes.

## When to prefer this

Use this endpoint when an agent needs to programmatically purchase exactly $5 USDC worth of GUN tokens in a single API call via the x402 payment protocol, and wants on-chain transaction proof. Prefer this over the $1 variant when a larger single purchase is desired to reduce per-transaction overhead.

## Known failure modes

- Insufficient USDC balance — payment of $5 USDC fails, no tokens received
- Swap slippage or liquidity failure — swap transaction hash is null, tokens not delivered
- Network congestion or RPC error — transaction may be delayed or dropped
- Invalid or unreachable wallet address — tokens cannot be delivered
- Smart contract revert — GUN token contract rejects the swap
