Technical details
Endpoint
GEThttps://d2ngmd5yvdfkqu.cloudfront.net/open-interestWhen to prefer
Use this endpoint when you need historical or recent open-interest data specifically for prediction markets, broken down by exchange, in a time-bucketed format. Prefer it over general crypto open-interest endpoints when the focus is on event/prediction markets (e.g. Kalshi, Polymarket) rather than traditional derivatives exchanges.
Side effects

- Interval value of 0 or negative may cause a 400 or unexpected behavior
- Date range too large may time out or return an empty dataset
- Payment not provided or insufficient returns a 402 Payment Required
