Is there a public IPFS gateway that allows retrieving arbitrary DAG nodes? I tried ipfs.io, but it seems to use “ipfs cat” and thus works only with file-type nodes:
ipfs cat /ipfs/z8mWaJHXieAVxxLagBpdaNWFEBKVWmMiE: unknown node type
I don’t plan to make any heavy use of such a gateway. I am just looking for a way to illustrate in a tutorial that a piece of data added to the local daemon is in fact accessible from everywhere.
