## 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`):

Example prompt: Buy me $5 worth of DEV tokens (contract 0x64a3fc16f47d5c39D526eF40adEcc8C050751b07) right now using USDC and show me how many tokens I received and the transaction hashes.

## When to prefer this

Use this endpoint when you need to purchase exactly $5 USDC worth of DEV tokens in a single atomic API call with x402 micropayment support. Prefer this over the $1 sibling endpoint when you want a larger fixed purchase without configuring a custom amount. Choose the custom-amount endpoint if you need a different spend size.

## Known failure modes

- Payment not received or insufficient USDC balance — payment rejected before swap executes
- Swap transaction fails on-chain — swapTransactionHash may be null and message will indicate failure
- Token contract address unreachable or liquidity insufficient — swap cannot complete
- x402 payment protocol error — caller's wallet not configured for x402 payments
- Network congestion causes transaction timeout — sendTransactionHash present but swap pending
