## 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 button-money-limit-order-0312180f -d '<json body>'
```

Example prompt: Set a limit order to swap 100 USDC (token address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48) for ETH (token address 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2) and only execute it when the price hits 0.00035 ETH per USDC.

## When to prefer this

Use this endpoint when you need to automate a token swap that should only execute at a specific price point, rather than executing immediately at market price. Ideal for agents managing DeFi portfolios that need price-conditional trading logic without constant monitoring.

## Known failure modes

- Invalid token address format — returns 400 with address validation error
- Insufficient token balance or allowance — returns error indicating funds unavailable
- Limit price outside acceptable range or malformed — returns 400 with price validation error
- Unsupported token pair — returns error if the token pair has no available liquidity route
- Service unavailable — returns 503 if the order management system is down
- Payment failure — returns 402 if the $0.005 USDC payment is not provided
