## 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 1 USDC worth of nine tokens (contract 0x3a105f1247B27DED116B5d8dFe3D8e24151c1B07) right now using the x420.dev nine endpoint.

## When to prefer this

Use this endpoint when you want to purchase exactly 1 USDC worth of nine tokens in a single atomic call via the x402 payment protocol. Prefer the sibling 5 USDC endpoint for larger fixed purchases, or the custom-amount endpoint for arbitrary quantities.

## Known failure modes

- Insufficient USDC balance to cover the $1 payment — payment rejected
- x402 payment protocol error — facilitator or payment channel issue
- Token swap fails on-chain — swap transaction hash may be null
- Network congestion causes transaction timeout
- Invalid or missing wallet/payment credentials
