EIP-4844 blob sidecars.

    Quickstart

    Blobs is a drop-in replacement for the Consensus Layer /eth/v1/beacon/blobs endpoint. Pull EIP-4844 blob payloads by slot, head, or block root. Public endpoint, no API key, no auth header. Use it for L2 data-availability lookups, archive replay, or forensic investigation past your CL client's retention window.

    Pin a slot with /blobs/<slot>, a block root with /blobs/0x<root>, or follow chain head with /blobs/head. Add ?versioned_hashes=… to fetch only specific blobs from a block.
