range
object
required

The time span actually covered by the returned results โ€” from the first to the last matching data point โ€” specified in slots, epochs, and Unix timestamps.

This reflects the data that was found, not the range that was queried. When the response is 200 but no data is found, it falls back to the requested range, or to the full available history if no range was given. Some endpoints answer 404 instead when no data is found.

For arbitrary (custom) time-range queries the queried range is expanded outward to whole UTC days, so the covered range may be wider than requested. As stated above, the reported range still reflects the data that was actually found โ€” a touched UTC day with no data for the selected validators will not extend it.
