CMS NPI APIs

[Ben Irwin]

Everyone may already know this, but I thought it was great and I would like to see other healthcare services like this made available to the public.

The CMS has a couple of simple easy to use APIs that can look up the NPI numbers and provider information for synchronization with local provider information.

The Demo form is at: https://npiregistry.cms.hhs.gov/api/demo?version=2.1

The form has two examples at the bottom and I have added a couple here.

With a little curl programming or %Net.Httprequest in Cache this could be easily applied to keep the local NEW PERSON file up-to-date.

Thank you Ben. That is really nice.

Other favorite web services:
RxNorm: https://rxnav.nlm.nih.gov/RxNormAPIs.html#
Random User Generator: https://randomuser.me/
Httpbin lets you test your web clients: https://httpbin.org/

On doing HTTP requests from GT.M/YottaDB and Cache, I recommend using
libcurl. None of the systems deals well with TLS SNI extensions. I
didn't report the bug to Intersystems; I did for YottaDB:
https://gitlab.com/YottaDB/DB/YDB/-/issues/373. Intersystems Cache
does not do TLS session resumption either, so you are spending 200ms
re-negotiating the connection every time.

I wrote a libcurl extension to GT.M/YottaDB:
https://github.com/shabiel/fis-gtm-plugins/tree/master/libcurl.

I also wrote a command line wrapper to curl, and included it in my
port of HWSC, at https://github.com/shabiel/HWSC/.

I tried to fix the issues with the XTHC code, but there were bugs
found after my release, and I never went back to fix them. You can
find your way to my buggy code here:
