Quickstart

The Loris Tools API gives you crypto derivatives data — funding rates, open interest, liquidations, and market snapshots — 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/funding

Response

You'll get a JSON object with funding rates keyed exchange-first, then symbol. On the free tier only BTC and ETH are returned. All values are 8-hour-normalized basis points (bps) — divide by 10,000 to get the raw decimal rate.

funding_intervals is the venue's native settlement interval in hours. Rates are already normalized to 8h equivalents regardless.
