https://enact.lcp.com/series/api/GbIndexData

This endpoint returns the daily revenues of a specified Index (see Enact's GB index page).

The indices have been backfilled from 1st January 2020 and include daily data up to and including yesterday.

To access the data of a specified index, you'll need its corresponding GUID which can be found by clicking the ID icon next to an index on the GB index page.
