Hyperliquid API

The Hyperliquid API is a zero-custody, REST-based trading API built by QuickNode specifically for the Hyperliquid exchange ecosystem. It is not a general-purpose blockchain node or RPC service, its sole focus is enabling developers to construct, sign, and submit trading orders for perpetuals, spot markets, and HIP-3 community perpetual markets programmatically. The API follows a strict build → sign → send workflow: developers first build unsigned order payloads through the API, sign them locally using their own private keys, and then submit the signed payloads for execution on Hyperliquid. This architecture guarantees that private keys never leave the developer's own environment at any point in the process.

The service provides developers with a comprehensive set of trading primitives and market data tools, including market orders, limit orders, stop-loss and take-profit orders, TWAP execution, position closing, order modification, batch cancellation, and open order management. Additional endpoints offer preflight validation to check orders before signing, order status lookups with plain-English explanations, and market listing for all available perp, spot, and HIP-3 instruments. The API charges a builder fee of 0.04% on perpetual trades and 0.05% on spot trades, on top of Hyperliquid's native exchange fees, with developers approving a maximum fee rate ceiling that can be revoked at any time.

What sets the Hyperliquid API apart is its zero-custody architecture and developer-centric design. Official SDKs are available for Python, TypeScript, Rust, and Go, and since the API operates over standard HTTPS REST, it is compatible with any environment capable of making HTTP requests and performing local cryptographic signing. It is worth noting that hyperliquidapi.com is an independent service and is not affiliated with Hyperliquid Corp or the Hyper Foundation. With clear documentation, interactive API explorers, and example integrations, the platform is well suited for algorithmic trading bots, automated trading systems, DeFi applications, and any workflow requiring secure, programmatic interaction with Hyperliquid's exchange markets.
