# Validators

> Querying into individual validator indices or aggregations of validator indices.

<Note>
  The RatedAPI allows you to aggregate stats on validator indices on-the-fly. Head on over to [Aggregating validator indices](/rated-api/api-reference/v0/ethereum/validators/get-effectiveness-aggregation) to learn more.
</Note>

The Validators class is the lowest order of aggregation that the Rated API supports. The [effectiveness](/rated-api/glossary/ethereum/effectiveness) endpoint returns you all kinds of useful information (e.g. rewards, performance etc) about a specific validator index, in the requested time-frame.
