Pulling census geography via API


I saw this post (https://acsdatacommunity.prb.org/discussion-forum/f/forum/415/possible-to-use-api-to-get-the-geography-file) and was wondering if anyone had more recent information on this. I'm trying to use Census geography as a lookup to standardize names and incorporate FIPS to 2-1-1 data.

An alternative might be to download TIGER or CSV files but keeping up those files might be time-consuming....not sure.

Any ideas/suggestions?

Thanks in advance!
