Exchange endpoint

The exchange endpoint is used to interact with and trade on the Hyperliquid chain. See the Python SDK for code to generate signatures for these requests.

Many of the requests take asset as an input. For perpetuals this is the index in the universe field returned by themeta response. For spot assets, use 10000 + index where index is the corresponding index in spotMeta.universe. For example, when submitting an order for PURR/USDC, the asset that should be used is 10000 because its asset index in the spot metadata is 0.

Place an order

POST https://api.hyperliquid.xyz/exchange

See Python SDK for full featured examples on the fields of the order request.

For limit orders, TIF (time-in-force) sets the behavior of the order upon first hitting the book.

ALO (add liquidity only, i.e. "post only") will be canceled instead of immediately matching.

IOC (immediate or cancel) will have the unfilled part canceled instead of resting.

GTC (good til canceled) orders have no special behavior.

Client Order ID (cloid) is an optional 128 bit hex string, e.g. 0x1234567890abcdef1234567890abcdef
