/eth/v1/validator/aggregate_attestation

Get aggregated attestation.

Combines all attestations that correspond to a specific attestation data root and slot.

If the block specified by the beacon_block_root answer is optimistic (i.e., the aggregated attestation attests to a block that has not been fully verified by an execution engine), a 503 error has to be returned.
