Indices

Get index history

Returns published values of an Attention Index within a time range, oldest first.

With interval=raw, every published value is returned. With a sampled interval, values are grouped into buckets aligned to the Unix epoch in UTC, and the last value in each bucket is returned.

When more values match than limit, the most recent ones are returned. An unknown index name returns an empty array.
