Packaged funding-rate history for one crypto perpetual on one venue, bundled per
Packaged funding-rate history for one crypto perpetual on one venue, bundled per time bucket at 1h/4h/1d granularity over up to 30 days — one paid call instead of stitching hundreds of hourly requests. Each bucket carries the average rate, sample count and average perp price. Order-book fields were withdrawn on 2026-09-16: include_orderbook=true is refused before payment, never silently ignored.
