--- title: "GetBeaconBlindedBlocksByBlockId" method: GET path: "/{apiKey}/eth/v1/beacon/blinded_blocks/{blockId}" --- # GetBeaconBlindedBlocksByBlockId `GET /{apiKey}/eth/v1/beacon/blinded_blocks/{blockId}` Get blinded block. Retrieves blinded block for given block ID. Depending on `Accept` header it can be returned either as JSON or as bytes serialized by SSZ. ## Path parameters - `apiKey` string, required — For higher throughput, please create your own API key. - `blockId` string, required ## Response `200` The state SSZ HashTreeRoot - object - `version` 'phase0' | 'altair' | 'bellatrix' | 'capella' | 'deneb', required - `execution_optimistic` boolean, required — True if the response references an unverified execution payload.
