Blob Archive API
Blob Archive API is a Blocknative service that retrieves and returns blob data from the Ethereum mempool, including confirmed and unconfirmed blobs.

What is Blob Archive API?
The Blob Archive API is a Blocknative service that stores all blobs entering the Ethereum mempool—confirmed on-chain or not—using its global network of nodes. Given any `versionedHash` of an on-chain blob, the archive returns the versioned hash, commitment, proof, count of zero-bytes, count of non-zero bytes and blob data. If users only want a summary view of the blob data, the archive can return the response without the full blob data.
