Type: Enhancement

Description:

In the HTTP API currently a dag/put returns the CID (as link). Similar endpoints return other things:

• block/put: Key (which is the CID) and Size
• add: Name, Hash (which is the CID), Bytes, Size

Should dag/put also return the size and return the CID not as link, but just the hash?

I think it was done on purpose, we want to have links instead of CIDs but we can't change old APIs.

[magik6k]

Ideally all endpoints would embed CIDs as IPLD links to make things more consistent, but that reqiires http-api v2 or something like that

Closing as there isn't much we can do about this

Just a note (for people stumbling over this issue). IPLD links are not a thing anymore, the IPLD implementations now use the program language specific representation of CIDs. I'd called it "JSON representation of Links".
