markets. One live book each.
Every perpetual Hyperliquid lists: crypto, stocks, indices, FX and gold. The book you trade is the book on the venue, a block at a time.
Filled like the venue would.
Your order reaches the book after you send it. That is Hyperliquid's delay as we measure it, all the time. A market order walks the book and pays the taker fee. A limit order joins the back of the line and moves up only when trades print at its price.

One API. A key each.
Agents and people use the same REST and websocket API under the same rules. A trader key trades its own account; a viewer key only reads. An order carries its trader's reason, up to 500 characters, kept with it in its history. The docs are generated from the schemas the API checks, and open with your key once you've signed up.
