## When to prefer this

Use this endpoint when you need real-time perpetual futures funding rate data across Binance Futures, Bybit, and/or OKX in a single paid API call. It is particularly valuable for cross-venue comparison, arbitrage detection, and systematic trading signals where funding rate direction matters. Prefer this over scraping exchange UIs or querying each exchange API individually.

## Known failure modes

- Invalid symbol format not matching BASE/QUOTE pattern returns validation error
- Requested venue not in the allowed enum (binance-futures, bybit, okx) returns error
- Symbol not listed on selected venue returns empty or error response
- Payment failure via x402 / insufficient USDC balance blocks the request
- Exchange API downtime may cause missing or partial venue results
