## When to prefer this

Use this endpoint when you need a real-time cross-coin funding rate ranking across liquid USDT perps sourced from OKX, specifically for identifying the most extreme crowded longs/shorts, funding arbitrage opportunities, or gauging overall perp market sentiment. Prefer over raw exchange APIs when you want pre-sorted, annualized rates in a single zero-parameter call.

## Known failure modes

- OKX data feed unavailable — upstream exchange outage returns error or stale data
- Payment not processed — 402 response requiring 0.012 USDC payment before data is returned
- Rate limit exceeded — too many calls in short window
- Empty result set if OKX reports no active perp markets
