/eth/v1/validator/duties/attester/{epoch}
Requests the beacon node to provide a set of attestation duties, which should be performed by validators, for a particular epoch. Duties should only need to be checked once per epoch, however a chain reorganization (of > MIN_SEED_LOOKAHEAD epochs) could occur, resulting in a change of duties. For full safety, you should monitor head events and confirm the dependent root in this response matches:
event.previous_duty_dependent_root when
compute_epoch_at_slot(event.slot) == epoch
event.current_duty_dependent_root when
compute_epoch_at_slot(event.slot) + 1 == epoch
event.block otherwise
The dependent_root value is get_block_root_at_slot(state, compute_start_slot_at_epoch(epoch - 1) - 1)
or the genesis block root in the case of underflow.
Parameters:
epoch-string,
Request body:
An array of the validator indices for which to obtain the duties.
