## 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 dog-x420-dev-02740ac1 -d '<json body>'
```

Example prompt: Buy me 1 USDC worth of DOG tokens — use the on-chain swap at contract 0xC6BCf27D02B724ad9869f138b1A41024648E4b07 and tell me how many tokens I received and the transaction hash.

## When to prefer this

Use this endpoint when an agent needs to autonomously purchase exactly 1 USDC worth of DOG tokens on-chain via an x402 micropayment flow, and wants back the token amount received plus on-chain transaction hashes for both the payment and the swap.

## Known failure modes

- Insufficient USDC balance — payment cannot be processed
- Smart contract swap failure — swap transaction hash is null and tokens not received
- Network congestion causing transaction timeout
- Invalid or unreachable contract address
- x402 payment protocol failure — USDC transfer rejected
