What this example covers

  • Hyperliquid REST API JavaScript example.
  • Uses the Siebly Hyperliquid SDK package @siebly/hyperliquid-api instead of hand-written HTTP request plumbing.
  • Source path: Hyperliquid/Rest/rest-spot-order.ts.
  • Imports SDK symbols including RestClient.
  • Calls SDK methods such as getSpotBalances(), submitLimitOrder(), getOrderStatus(), cancelOrders().

How to use this example

  • Start here for the specific request or stream pattern, then check the matching SDK guide for install, credentials, and operational notes.
  • Open the repository source when you need the latest committed version: GitHub source file.
