I am getting used to using python-cloudant for authenticated access to Cloudant databases but want to do unauthenticated access from a Python script. I set up unauthenticated read access to one of the databases for my account and can read documents fine using curl without authentication but I don't know how to do this using python-cloudant. I've tried using (None, None), ("nobody", "none"), even some credentials that I use for databases for a completely different account but get denied access.
I think I got the right combination. I don't know what I was doing earlier but when I authenticate with a valid API key & access token, I got access even though the API key doesn't have explicit access to the database.
