Hyperliquid (HYPE) API Documentation

Hyperliquid

Hyperliquid (HYPE) is a Layer 1 using HyperBFT consensus, with execution split between HyperCore and the general-purpose HyperEVM inside the same blockchain state. HyperEVM runs EVM bytecode and Ethereum-style account storage, while HyperCore maintains order books, margin, positions, and other exchange state; nodes execute and synchronize both components. This unified model gives applications standard EVM transaction and contract semantics alongside native trading-state primitives that do not exist in a conventional EVM-only chain.

Hyperliquid API Methods and Endpoints

NOWNodes exposes Hyperliquid's interface, plus a few others, depending on what your integration needs: JSON-RPC for reading chain state and broadcasting transactions.

Browse the interfaces below for endpoint details, request parameters, response formats, and integration examples. Create an API key, select Mainnet or Testnet, choose the required interface, and start sending requests from your application.
