## 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-5-usdc-x420-dev-d318d1c4

Example prompt: Buy me $5 worth of BNB tokens right now — use 5 USDC and send the BNB to my wallet 0xB61C31F4F336ADC22E5d4C47e1520B34ffeeFb07.

## When to prefer this

Use this endpoint when an agent needs to purchase exactly $5 USDC worth of BNB tokens in a single on-chain transaction via the x402 pay-per-call protocol. Prefer this over the $1 variant when the user wants a larger minimum purchase in a single call. Ideal for agents automating crypto portfolio rebalancing or acquiring BNB for gas fees on BNB Chain.

## Known failure modes

- Insufficient USDC balance — payment of 5 USDC cannot be completed
- Network congestion causing swap transaction to fail or timeout
- Invalid or unreachable wallet address
- Liquidity pool slippage causing swap to revert
- x402 payment protocol error if payment header is malformed
- Swap transaction hash may be null if the swap is pending or failed post-payment
