## 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-5-usdc-x420-dev-84aed3ab

Example prompt: Buy me 5 USDC worth of ROLLAK tokens using the x420.dev puff endpoint — I want to pick up some ROLLAK (contract 0x287f28Ea9740D09cdff1ddd1faC4209fc40BdB07).

## When to prefer this

Use this endpoint when you want to purchase a fixed amount of exactly 5 USDC worth of ROLLAK tokens in a single call. Prefer the 1 USDC sibling for a smaller test purchase or the custom-amount endpoint when you need a different spend amount. This fixed-denomination endpoint is simpler to invoke when 5 USDC is the desired spend.

## Known failure modes

- Insufficient USDC balance to cover the 5 USDC payment
- Payment transaction fails or times out, sendTransactionHash returned as null
- Swap transaction fails on-chain, swapTransactionHash returned as null
- Token contract liquidity too low to complete the swap
- x402 payment protocol error or facilitator rejection
