Oracle price-source family classification across tracked crypto perp venues — which venues derive their index price from the same upstream feed.

Live perpetual-futures funding rates per venue for one crypto symbol, or the whole cross-venue set in one call. Major CEX and DEX perp venues — Binance, Bybit, OKX, Bitget, Gate.io, KuCoin, Hyperliquid, Paradex, Drift, Orderly, Lighter and more. Each row carries the venue's current rate, its funding interval and the 8h-equivalent rate (venues quote on 1h/4h/8h schedules, so the raw rates are not comparable without it), plus canonical_id, asset_class and mark_price so a ticker that names two unrelated assets is visible rather than silently mixed.
