Path Parameters

epoch

integer

REQUIRED

The epoch value for which to request sync committee duties.

Body Parameters

validator_indices

array

REQUIRED

An array of validator indices for which to obtain sync committee duties. Each index identifies a specific validator in the beacon chain's validator registry

Returns

execution_optimistic

boolean

Whether the response is based on optimistic or finalized data. If true, the duties response is based on the optimistic (non-finalized) head. Clients should wait for finalization if they need stronger guarantees

data

array

Array of validator sync committee duties, one entry per requested validator that is selected for sync committee duties in the specified epoch

pubkey

string

The validator's BLS public key, encoded as a hexadecimal string with '0x' prefix

validator_index

string

Index of the validator in the beacon state's validator registry, represented as a string containing a decimal number

validator_sync_committee_indices

array

Array of indices indicating the validator's positions within the sync committee. A validator may have multiple positions. Each index is represented as a string containing a decimal number from 0 to 511 (sync committee size - 1)
