+Requests sidecars by block root and index.
+The response is a list of `DataColumnIdentifier` whose length is less than or equal to the number of requests.
+It may be less in the case that the responding peer is missing blocks or sidecars.
+
+Before consuming the next response chunk, the response reader SHOULD verify the data column sidecar is well-formatted, has valid inclusion proof, and is correct w.r.t. the expected KZG commitments through `verify_data_column_sidecar_kzg_proofs`.
+
+No more than `MAX_REQUEST_DATA_COLUMN_SIDECARS` may be requested at a time.
+
+The response MUST consist of zero or more `response_chunk`.
+Each _successful_ `response_chunk` MUST contain a single `DataColumnSidecar` payload.
+
+Clients MUST support requesting sidecars since `minimum_request_epoch`, where `minimum_request_epoch = max(finalized_epoch, current_epoch - MIN_EPOCHS_FOR_DATA_COLUMN_SIDECARS_REQUESTS, EIP7594_FORK_EPOCH)`. If any root in the request content references a block earlier than `minimum_request_epoch`, peers MAY respond with error code `3: ResourceUnavailable` or not include the data column sidecar in the response.
+
+Clients MUST respond with at least one sidecar, if they have it.
+Clients MAY limit the number of blocks and sidecars in the response.
+
+Clients SHOULD include a sidecar in the response as soon as it passes the gossip validation rules.
+Clients SHOULD NOT respond with sidecars related to blocks that fail gossip validation rules.
+Clients SHOULD NOT respond with sidecars related to blocks that fail the beacon chain state transition
