REST API

Base URL

https://hyper.polynode.dev/v2/

All endpoints require an API key via x-api-key header or ?key= query parameter.

Three tiers of speed

hypernode serves data from three sources, each with different performance characteristics:

Cached

15 endpoints. Data cached in memory, refreshed every 1-60 seconds. 12,000+ req/sec. L4 order book, market metadata, DeFi rates.

Local node

22 endpoints. Queries our local HyperLiquid node directly. 4ms latency. User state, positions, open orders, fees.

External proxy

17 endpoints. Proxied to HyperLiquid API for data not available locally. L2 orderbook, candles, trade history.
