## 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-7aa868c2
```

Example prompt: Generate me a zero-capital flash loan strategy for a USDC/ETH arbitrage using Aave V3 — I need the full execution calldata and an executor contract template I can deploy directly.

## When to prefer this

Use this endpoint when an autonomous DeFi agent needs ready-to-execute flash loan calldata and contract templates with zero capital requirements, specifically targeting Aave V3 or Balancer protocols, rather than just opportunity discovery or yield comparison endpoints.

## Known failure modes

- Invalid or unsupported asset pair — no calldata returned
- Protocol unavailable or insufficient liquidity — strategy not constructable
- Missing required strategy parameters — 400-level error
- Flash loan amount exceeds available pool liquidity
- Malformed request or unsupported chain — error response

## How this service works

Zero-capital flash-loan strategy builder — execution calldata for Aave V3 and Balancer with executor-contract templates. For autonomous DeFi agents.

## Output

Returns execution calldata ready for on-chain submission, an executor smart contract template, flash loan parameters (amounts, assets, protocols), and gas estimates — all targeting Aave V3 or Balancer, structured for direct autonomous agent execution.
