# GetBeaconStatesRandaoByStateId

`GET /{apiKey}/eth/v1/beacon/states/{stateId}/randao`

Get the RANDAO mix for some epoch in a specified state.

Fetch the RANDAO mix for the requested epoch from the state identified by `state_id`.

If an epoch is not specified then the RANDAO mix for the state's current epoch will be returned.

By adjusting the `state_id` parameter you can query for any historic value of the RANDAO mix.
Ordinarily states from the same epoch will mutate the RANDAO mix for that epoch as blocks are
applied.
