## When to prefer this

Choose this endpoint when you need a quick cross-exchange scan for outlier funding rate conditions rather than full historical rates. Ideal for identifying crowded trades, mean-reversion setups, or market stress events. Prefer /extremes over /rates when you only care about the tail ends of the distribution and want a pre-filtered signal rather than the full rate table.

## Known failure modes
