## 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 yaoming-token-purchase-5-usdc-x420-dev-a120a25b

Example prompt: Buy $5 worth of Yaoming tokens (contract 0x73DB2BE4581BcE956501eD0e2156DC31939B2b07) for me right now using USDC via x420.dev.

## When to prefer this

Use this endpoint when you want to purchase exactly $5 USDC worth of Yaoming tokens in a single fixed-amount call, rather than the $1 tier or a custom amount. Prefer this over the custom-amount endpoint when the desired spend is exactly $5 and simplicity is preferred over flexibility.

## Known failure modes

- Insufficient USDC balance — payment of $5 cannot be fulfilled
- x402 payment protocol error — payment header missing or invalid
- On-chain swap failure — swap transaction reverts or times out
- Contract address mismatch or token liquidity too low
- Network congestion causing transaction hash to be null on response
