## Tools
- perp_scan_funding_arbitrage - Use this when you need to find funding rate arbitrage opportunities across perpetual exchanges. Returns cross-venue spreads in JSON.

1. opportunities: array of arb opportunities ranked by annualized yield
2. symbol: asset symbol (BTC, ETH, SOL, etc.)
3. longExchange: exchange where you go long (lower funding)
4. shortExchange: exchange where you go short (higher funding)
5. spread: funding rate difference between venues
6. annualizedYield: estimated annualized return from the arb
7. direction: suggested position direction per exchange

Example output: {"opportunities":[{"symbol":"ETH","longExchange":"Bybit","shortExchange":"OKX","spread":0.0045,"annualizedYield":16.4,"direction":"long Bybit / short OKX"}],"scannedAssets":25,"timestamp":"2026-04-13T12:00:00Z"}

Use this FOR systematic funding rate arbitrage and delta-neutral carry strategies. Scans all major perpetual venues simultaneously.
