## 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 rollak-token-purchase-1-usdc-x420-dev-dd0553ae
```

Example prompt: Buy me 1 USDC worth of ROLLAK tokens right now — use the x420.dev ROLLAK endpoint and tell me how many tokens I received and the transaction hashes.

## When to prefer this

Use this endpoint when you want to purchase a fixed small amount (1 USDC) of ROLLAK tokens automatically via an x402-enabled agent without needing to manually configure a swap amount. Prefer the custom-amount sibling endpoint if the desired purchase amount differs from exactly 1 USDC.

## Known failure modes

- Insufficient USDC balance — payment cannot be processed
- Smart contract swap failure — swapTransactionHash is null and message indicates error
- Network congestion causing transaction timeout
- Invalid or paused ROLLAK token contract
- x402 payment protocol rejection — HTTP 402 if payment not provided or invalid
