Usenami · Funding Current

api.usenami.io

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.

Usenami · Perp Basis

api.usenami.io

Per-venue basis for one crypto perpetual — mark versus index price, basis_bps = (mark−index)/index×10000, and contango/backwardation structure, across tracked CEX and DEX perp venues. Every venue comes with an index except Crypto.com, Variational and dYdX; dYdX publishes one oracle price, and that price is its mark. `venues_without_index` names the ones missing from your response. Each venue also carries liquidity_state (live/dead/unknown), and a market with no trading is flagged unreliable however clean its basis looks.
