--- title: "Get block" method: GET path: "/eth/v2/beacon/blocks/{block_id}" tags: ["Beacon"] --- # Get block `GET /eth/v2/beacon/blocks/{block_id}` ## Request - Base URL: `eth2-beacon-mainnet.nodereal.io/v1/api_key` (relative, and the document’s source URL is not known) - URL: `eth2-beacon-mainnet.nodereal.io/v1/api_key/eth/v2/beacon/blocks/{block_id}` - Auth: none declared Retrieves block details for given block id. Depending on `Accept` header it can be returned either as json or as bytes serialized by SSZ ## Path parameters - `block_id` string, required ## Response `200` Successful response - object - `version` 'phase0' | 'altair' | 'bellatrix' - `execution_optimistic` boolean: True if the response references an unverified execution payload. Optimistic information may be invalidated at a later time. If the field is not present, assume the False value. - `data` union - object: The [`SignedBeaconBlock`](https://github.com/ethereum/consensus-specs/blob/v1.0.1/specs/phase0/beacon-chain.md#signedbeaconblock) object envelope from the CL spec. -
