Countries and their country codes

[NerfBro]

I can get the list of countries and another, separate list of country codes (now needed for filtering searches), but how can i get a list of countries AND their codes together in a single associative list? I'm asking because I need the country name to show the user in my UI, and I need the code to do the filtered lookup using the API.
