Example prompt: Scan all chains for the best cross-protocol DeFi yield arbitrage right now — show me borrow/deposit spread opportunities with the highest net APY, ranked by profitability.

## When to prefer this

Use this endpoint when you need to find yield arbitrage opportunities specifically in DeFi lending/borrowing markets across multiple chains. Prefer this over the top-opportunities aggregator when you want to focus exclusively on borrow/deposit spread mechanics rather than DEX or perps arbitrage. Best for agents building DeFi yield strategies or monitoring lending protocol rate differentials.

## Known failure modes

- No live rate data available for requested chain or protocol (404 or empty result)
- Rate data stale or temporarily unavailable (503)
- Payment not processed or insufficient USDC balance (402)
- Invalid or unsupported chain/asset parameter (400)
- All spreads below minimum threshold — no profitable opportunities found

## Output

A ranked list of borrow/deposit spread arbitrage opportunities across DeFi lending protocols on multiple chains, including protocol names, chains, assets, borrow rates, deposit rates, net spread/APY, and opportunity sizing.
