IOTA Notarization Verify

Verify an IOTA notarization: give the object id or transaction digest of any notarization on the IOTA mainnet (ours or anyone's, official IOTA Notarization package) and optionally the text, SHA-256 or URL to check. Returns the stored hash or data, creation time from the ledger, lock status (can it be changed or deleted), owner, and matches true or false for your content. Read-only, no wallet needed.
