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.
Asset
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.
Subaccounts and vaults
Subaccounts and vaults do not have private keys. To perform actions on behalf of a subaccount or vault signing should be done by the master account and the vaultAddress field should be set to the address of the subaccount or vault. The basic_vault.py example in the Python SDK demonstrates this.
Expires After
Some actions support an optional field expiresAfter which is a timestamp in milliseconds after which the action will be rejected. User-signed actions such as Core USDC transfer do not support the expiresAfter field. Note that actions consume 5x the usual address-based rate limit when canceled due to a stale expiresAfter field.
See the Python SDK for details on how to incorporate this field when signing.
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
