## 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 bnb-token-purchase-x420-dev-1-usdc-e7822485
```

Example prompt: Buy me 1 USDC worth of BNB tokens right now — go ahead and execute the swap and let me know how many BNB I received and what the transaction hash is.

## When to prefer this

Use this endpoint when you need to acquire a small amount of BNB (Binance Coin) by spending exactly 1 USDC, especially in automated or agent-driven workflows that support x402 micropayment protocol. Prefer the 5 USDC sibling endpoint if you need a larger BNB purchase in a single call.

## Known failure modes

- Payment not received or USDC balance insufficient — transaction fails with error message
- Swap fails due to low liquidity or slippage — swapTransactionHash is null and message contains error
- Network congestion causes timeout — sendTransactionHash returned but swapTransactionHash null
- Invalid wallet address configured — transaction cannot complete
- x402 payment protocol error — 402 response before API call is processed
