## 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-dex-cross-chain-arbitrage-scanner-fd0a3668
```

Example prompt: Scan for live cross-chain DEX arbitrage opportunities on ETH/USDC right now — include flash-loan execution paths across all available pools and chains so I know exactly how to capture the spread.

## When to prefer this

Choose this endpoint when you need real-time cross-pool and cross-chain DEX arbitrage opportunities with ready-to-execute flash-loan paths. Prefer this over CEX arbitrage endpoints when you want onchain, zero-capital execution routes. Best for MEV agents and DeFi bots that need both opportunity detection and calldata in one call.

## Known failure modes

- No arbitrage opportunity found for the requested pair at this moment — market may be efficient
- Invalid token pair or unsupported chain returns 400 error
- Opportunity expired between scan and response due to block finality — stale spread warning
- Flash loan liquidity insufficient for the detected spread size
- Rate limit or payment failure returns 402 or 429 status

## How this service works

Cross-pool and cross-chain DEX price arbitrage, with flash-loan execution paths. For DeFi and MEV agents.

## Output

Returns current arbitrage opportunities across DEX pools and chains, including the price spread, estimated profit, optimal execution path, and flash-loan calldata (e.g. via Aave V3 or Balancer) needed to capture the opportunity with zero capital.
