hyperliquid-api-reference

Solid

Compact reference for the Hyperliquid API as the desk uses it - endpoints and envelopes, every /info request type, every /exchange action with its signing scheme, order and status vocabularies, asset ids, tick and lot rules, rate limits, WebSocket subscription list, error strings, and where the official docs are. Use to look up an exact field, request type or limit before writing a call, and to map an error string to its cause.

# Hyperliquid API reference (desk edition) Verified against the official docs on 2026-08-16.

Unknown `type` or missing field: HTTP 422; invalid JSON: HTTP 400. - `POST /exchange` body `{"action": {...}, "nonce": <ms>, "signature": {"r","s","v"}, "vaultAddress"?: "0x...", "expiresAfter"?: <ms>}`; response `{"status":"ok","response":{"type":"order"|"cancel"|"default"|..., "data"?: {...}}}` or `{"status":"err","response":"<string>"}`, both HTTP 200. - Header `Content-Type: application/json`. ## /info request types | type | params | returns | | --- | --- | --- | | `allMids` | `dex?` | `{coin: midPx}` | | `meta` | `dex?` | `{universe:[{name, szDecimals, maxLeverage, marginTableId?, onlyIsolated?, marginMode?, isDelisted?}], marginTables:[[id,{description, marginTiers:[{lowerBound, maxLeverage}]}]]}` | | `metaAndAssetCtxs` | `dex?` | `[meta, [{funding, openInterest, pre...
