Get CeFi instrument price history

GET 
/v1/cefi/market/prices/history

Returns historical bid/ask midpoint prices for a CeFi instrument over a configurable lookback window, sampled at a configurable resolution. Each price is (bid + ask) / 2 from the latest EBBO snapshot in the bucket; buckets without both a bid and an ask are excluded.

The symbol parameter is the venue-native instrument symbol (e.g. BTC-USD) — there is no registry translation today.

See the Time Window & Resolution section for the format of window and resolution.
