The HDL API is coming soon. The details on this page describe the planned service and may change before launch.
HDL will be available as a market data source for perpetual futures builders and platforms, free of charge. Use the same consolidated book that prices fills on Hyperprop as the reference for your own product.

​
What you get

HDL data will be delivered over WebSocket for live streams and REST for queries and history:
  • Prices: live best bid, best ask and last price.
  • Order books: the consolidated HDL book.
  • Candles: live and historical candles.
  • Status: whether each instrument is currently published.
Every key covers all HDL symbols. See Supported markets.

​
Access

Access is by partner API key, issued by Hyperprop.
1

Request access

Contact Hyperprop with your company, your product and how you plan to use HDL data.
2

Receive your key

Hyperprop issues a partner API key for your backend.
3

Connect from your backend

Use the key from your servers to stream and query HDL, then serve the data to your own users.
HDL keys are for backend-to-backend use only. Never embed a key in a browser, a mobile app or any other client you distribute. Connections from browsers are not supported.

Limits per key

​
Endpoints

Endpoint URLs, message formats and the full reference will be published in these docs when the API launches.
