Hyperliquid L4 Data Now Available via CoinAPI
CoinAPI has expanded its market data offering with native Hyperliquid Level 4 (L4) data, providing access to unaggregated order-level activity across one of the fastest-growing decentralized trading ecosystems.
The new integration delivers complete order lifecycle visibility, allowing users to monitor individual order placements, modifications, cancellations, partial fills, executions, and participant attribution in real time.
Unlike traditional Level 1 and Level 2 market data feeds, Hyperliquid L4 exposes the underlying mechanics of market activity rather than only the final state of the order book.
What the Integration Includes
The Hyperliquid L4 offering consists of six dedicated real-time feed families:
- book_l4 – Full Level 4 order book snapshots and incremental updates
- trade_l4 – Executed trades with maker and taker attribution
- hl_oracle_prices – Oracle and mark price updates
- hl_twap_statuses – TWAP lifecycle and execution progress events
- hl_misc_events – Raw exchange event streams
- hl_system_events – Raw system-level event streams
All feeds are available through a dedicated WebSocket DS endpoint and can be consumed through a single connection.
Key Data Elements
The integration provides access to:
- Individual order lifecycle events
- Persistent order identifiers
- Wallet-level participant attribution
- Time-in-force instructions
- Reduce-only flags
- Trigger prices and trigger conditions
- Parent-child order relationships
- Oracle and mark price updates
- TWAP execution status data
- Raw exchange and system events
This level of detail enables complete reconstruction of market activity and order book state.
Historical and Real-Time Access
Hyperliquid L4 data is available through both:
- Real-time WebSocket DS streaming
- Historical flat-file datasets delivered via AWS S3
The two delivery methods use aligned schemas and field naming conventions, simplifying the transition between research, backtesting, and production environments.
What This Enables for Trading and Research
Most market data products provide aggregated views of liquidity. Hyperliquid L4 exposes the underlying order flow that creates that liquidity.
This allows teams to:
- Reconstruct complete order books
- Analyze order cancellation behavior
- Study liquidity creation and withdrawal
- Monitor wallet activity
- Build market microstructure models
- Perform execution quality analysis
- Conduct quantitative research using order-level data
For trading firms, researchers, and infrastructure providers, access to unaggregated order flow offers a significantly deeper view of market behavior than traditional market data feeds.
Availability
CoinAPI's new Hyperliquid L4 integration provides one of the deepest views available into Hyperliquid market structure, exposing every stage of the order lifecycle rather than just the final result.
If you're building trading systems, conducting market microstructure research, analyzing liquidity behavior, or searching for signals hidden beneath aggregated order books, Hyperliquid L4 data offers an entirely new layer of visibility.
