Oracle price-source family classification across tracked crypto perp venues — which venues derive their index price from the same upstream feed. Basis-risk awareness for cross-venue and funding-arb strategies: two venues sharing an oracle family will not diverge independently, so a spread between them is not the hedge it looks like.

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 venues. Every venue has an index except Crypto.com, Variational and dYdX; dYdX publishes one oracle price, which is its mark. `venues_without_index` names the ones missing. Each venue also carries liquidity_state (live/dead/unknown), and a market with no trading is flagged unreliable however clean its basis looks.

Funding-rate sign-change detection for one crypto perpetual — every positive↔negative flip across venues inside a lookback window, each with its venue, hour and the rates either side of the change. Raw events for spotting funding-regime turns in funding-arb and carry positioning: it reports the flips, it does not classify them as sustained or transient.

Next funding payment ETA for one crypto perpetual on one venue, with the current indicative funding rate alongside — when the next settlement lands and where the rate stands now. Entry-timing input for funding-arb and carry trades. Not a payment forecast: the endpoint takes no position side or size, and the rate can move before settlement.

Cross-venue funding-rate spread for one crypto perpetual — the highest- and lowest-paying venues and the spread in bps, across major CEX and DEX venues (Binance, Bybit, OKX, Hyperliquid …). `spread_bps` is the RAW rate difference, the same quantity and name as on `/v1/perp/arbitrage/funding`; `normalized_spread_8h_bps` scales both legs to 8h, the comparable one, since venues quote on 1h/4h/8h. Leg intervals ship with the row; normalized is null when a schedule is unknown, never defaulted.

Funding rates per venue for one crypto perpetual, or the whole cross-venue set in one call. Major CEX and DEX venues — Binance, Bybit, OKX, Bitget, Gate.io, KuCoin, Hyperliquid, Paradex, Orderly, Lighter and more. Each row carries the venue's rate, its funding interval and the 8h-equivalent rate (venues quote on 1h/4h/8h, so raw rates are not comparable), plus canonical_id, asset_class and mark_price, so a ticker naming two unrelated assets is visible, not silently mixed.
