## 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 chewdoge-token-purchase-1-usdc-x420-dev-957751ee
```

Example prompt: Buy me 1 USDC worth of Chewdoge tokens right now — go ahead and execute the swap and give me the transaction hash.

## When to prefer this

Use this endpoint when an agent needs to acquire a small amount of Chewdoge tokens (1 USDC denomination) in a single automated call using the x402 micropayment protocol. Prefer the sibling 5 USDC endpoint when a larger purchase is desired. This endpoint is the minimum-spend option for Chewdoge token acquisition.

## Known failure modes

- Insufficient USDC balance to cover the 1 USDC payment — payment rejected
- x402 payment header missing or invalid — 402 Payment Required response
- Token swap fails on-chain — swapTransactionHash may be null with an error message
- Network congestion causes transaction timeout
- Contract address liquidity insufficient for swap execution
