Usenami
■ Challenge detectedFunding 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.

Base URLhttps:
- GET/perp
/arbitrage /funding-signal$0.005Funding-arb SIGNAL for crypto perpetuals — the cross-venue funding spread per pair, set against public round-trip taker fees, with periods-to-breakeven, ranked by the 8h-normalized spread. Liquidity is not assessed: depth sizing was withdrawn on 2026-09-16, so check the books before sizing. A derived outcome, not a profit forecast. - GET/funding
/current$0.001Funding 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. - GET/perp
/oracle-families$0.001Oracle 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. - GET/rwa
/perp-coverage$0.001Real-world-asset (RWA) perpetual coverage across HIP-3 DEXes — which stocks, metals, forex pairs, commodities and pre-IPO synthetics are listed as perps, and on which venue. Tracks the on-chain RWA perp surface as it expands beyond crypto. - GET/perp
/arbitrage /price$0.003Cross-venue mark-price spread scan for crypto perpetuals — where the same perp trades at different marks across venues. Quoted spread is not net edge: it excludes fees, slippage and funding differences. - GET/backtest
/data$0.05Packaged 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.
