Overview
The beaconcha.in API provides some data indexed by epoch. To better understand the relationship between time and epochs, you can use the Slot Finder tool and the time constants provided below.
We are developing endpoints designed to streamline the retrieval of summarized data for user-defined periods. Manually summing up rewards epoch-by-epoch doesn’t scale well for many validators over long timeframes.
