Resource model
Market data is organized around two resources:- Market — a tradeable instrument on a specific venue, keyed by a canonical slug
{venue}:{instrument_type}:{pair}, e.g.hl:perp:BTC-USDC,hl:spot:HYPE-USDC. - Asset — a canonical entity (e.g.
asset:bitcoin) that aggregates a token across all of its deployments and markets. Asset-keyed endpoints are coming soon.
instrument_type is one of perp or spot today. future and option are reserved for future use.
Supported venues
Hyperliquid is the only venue available today. Additional CEX and DEX
venues (e.g. Binance, dYdX, Uniswap) are coming soon — to request
prioritization of a specific venue, reach out to your account manager.
venue dimension simply grows, and the same market_id shape extends to new venues.
Conventions
- Decimals as strings
- Timestamps
- Pagination
All numeric response fields are returned as JSON strings to preserve
precision. Several values (notional, open interest in base units) exceed
JSON’s
2^53 safe-integer range, so parsing them as numbers would silently
round. Parse them with an arbitrary-precision decimal type.Authentication
All endpoints require an API key passed in theX-API-KEY header. The base URL is https://api.allium.so.
