## 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-x420-dev-3bb05be3 -d '<json body>'
```

Example prompt: Buy me $10 worth of yaoming tokens using USDC — use the custom amount option so I can specify exactly 10 USDC.

## When to prefer this

Use this endpoint when you need to purchase a specific custom USDC amount (not just the default $5) of Yaoming tokens (contract 0x73DB2BE4581BcE956501eD0e2156DC31939B2b07) on the Base network via x402 micropayment. Prefer this over the default endpoint when amounts other than $5 are desired.

## Known failure modes

- Missing X-PAYMENT header returns 402 with payment instructions and accepted asset details
- Invalid or insufficient USDC payment amount results in payment rejection
- Amount parameter not parseable as a decimal number causes input error
- Swap failure on-chain results in null transaction hashes and error message
- Network congestion on Base may cause timeout within 120 seconds
