## When to prefer this

Choose this endpoint when you need real-time or near-real-time funding rate and open interest data for crypto derivatives markets, especially for perpetual swaps. Useful for sentiment analysis, identifying crowded trades, or building trading signals. Prefer this over general price APIs when you specifically need derivatives-specific metrics like funding rates and OI rather than spot prices.

## Known failure modes

- Missing or invalid asset symbol returns an error or empty data object
- Rate limiting if too many requests are made without valid payment
- Invalid exchange parameter returns no data
- Stale data if market data feed is delayed
- Payment failure via x402/USDC results in 402 response blocking data access
