/eth/v1/beacon/blob_sidecars/{block_id} REST API Endpoint

The complete history of blob data is supported.

SSZ Response Support

This endpoint also supports SSZ (SimpleSerialize) responses. Set Accept: application/octet-stream in the request header to receive an SSZ-encoded payload instead of JSON. SSZ responses are smaller and faster to parse, and are useful for consensus-layer clients and indexers.

curl -X GET "YOUR_QUICKNODE_ETHEREUM_URL/eth/v1/beacon/blob_sidecars/{block_id}" \
    -H "Accept: application/octet-stream" \
