## 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 arbipulse-flash-loan-strategy-builder-42e72c6d
```

Example prompt: Build me a zero-capital flash loan strategy on Aave V3 to borrow 50,000 USDC, execute an arbitrage between Uniswap and Curve, and give me the executor contract template and calldata I can deploy right away.

## When to prefer this

Use this endpoint when you need to generate the actual on-chain calldata and smart contract templates for executing a flash loan arbitrage strategy with zero upfront capital, specifically targeting Aave V3 or Balancer protocols. Prefer this over the DEX price arbitrage or CEX arbitrage endpoints when you already have an opportunity identified and need the execution layer artifacts (calldata + contract) rather than opportunity discovery.

## Known failure modes

- Unsupported flash loan protocol specified — only Aave V3 and Balancer are supported
- Invalid token address or unsupported asset for flash loan
- Loan amount exceeds protocol liquidity limits
- Missing or malformed strategy parameters resulting in invalid calldata
- Payment of 0.75 USDC not processed — x402 payment required
- Strategy configuration produces unprofitable execution path
