API
Documentation for the Hyperliquid public API
You can also use the API via the Hyperliquid Python SDK: https://github.com/hyperliquid-dex/hyperliquid-python-sdk
All example API calls use the Mainnet url (https://api.hyperliquid.xyz), but you can make the same requests against Testnet using the corresponding url (https://api.hyperliquid-testnet.xyz)
The API currently uses some nonstandard notation. Relevant changes will be batched into a breaking v1 API change.
Abbreviation | Full name | Explanation |
|---|---|---|
Px | Price | |
Sz | Size | In units of coin, i.e. base currency |
Szi | Signed size | Positive for long, negative for short |
Ntl | Notional | USD amount, Px * Sz |
Side | Side of trade or book | B = Bid = Buy, A = Ask = Short. Side is aggressing side for trades. |
Asset | Asset | An integer representing the asset being traded. See below for explanation |
Tif | Time in force | GTC = good until canceled, ALO = add liquidity only (post only), IOC = immediate or cancel |
When requests expect an integer for
asset, use the index of the coin found in the meta info response. E.g. BTC = 0 on mainnet.Both Price (px) and Size (sz) have a maximum number of decimals that are accepted.
Prices are precise to the lesser of 5 significant figures or 6 decimals. For example,
1234.5 is valid but 1234.56 is not. 0.001234 is valid, but 0.0012345 is not.Sizes are rounded to the
szDecimals of that asset. For example, if szDecimals = 3 then 1.001 is a valid size but 1.0001 is not. You can find the
szDecimals for an asset by making a meta request to the info endpoint
