# Return all active contract series and interval pairs.

`GET /instrument/activeIntervals`

This endpoint is useful for determining which pairs are live. It returns two arrays of   strings. The first is intervals, such as `["XBT:perpetual", "XBT:quarterly", "XBT:biquarterly", "ETH:quarterly", ...]`. These identifiers are usable in any query's `symbol` param. The second array is the current resolution of these intervals. Results are mapped at the same index.
