How to tell which PeerID created a DAG block identified by CID

I wonder if there is a core API that returns more info about a CID, including the “author” PeerID.

Or alternatively, can I tell what CIDs, amongst the ones currently on my node, I have created using my key?

Thanks

No, IPFS default DAGs do not include information about who created them by default.

Thank you, Hector. I’ll keep track of my cids by adding them to MFS, or a directory that is identified by an IPNS.
