Perp funding-rate check, deterministic. Answers "what is the funding rate for this coin right now", "am I paying or earning to hold this perp", "which venue has the best funding".

Perp funding-rate check, deterministic. Answers "what is the funding rate for this coin right now", "am I paying or earning to hold this perp", "which venue has the best funding". One coin (or top markets by open interest): hourly funding, 8h-equivalent, annualized percent, open interest, mark price, premium — plus predicted funding across venues normalized to a comparable 24h rate. Keyless Hyperliquid public data. No LLM.

price-ascending: candidates are ordered by the listed price of the operation, with no managed-first preference applied. Unlike /v1/apis, this surface does not rank Apiosk-settled listings above federated ones — a comparison that reorders on commercial grounds is not a comparison. Pass sort=managed_first for the catalog's ordering.

Compared: listed price, settlement rail and input compatibility. Not measured yet: latency, reliability, result quality, and provider terms such as rate limits, jurisdiction and licensing.
