Quickstart
The Loris Tools API gives you crypto derivatives data — funding rates, open interest, liquidations, and order book data — across 43 venues, including 32 DEXes. It's the same data that powers loris.tools.
Get an API key
Sign up at loris.tools, then go to /account/api-keys and click Create key. The free tier works without a credit card and gives you live BTC and ETH data across all 43 venues.
Make your first call
Pass your key in the X-Api-Key header:
bash
curl -H "X-Api-Key: lk_live_your_key_here" \
https://api.loris.tools/fundingResponse
You'll get a JSON object keyed by symbol, with per-venue funding data nested inside. On the free tier, only BTC and ETH are returned:
