This is an API for lists of data. Specifically, general information that can be structured in simple lists and does not change too frequently.
Sure. Have you ever needed a list of all the countries and country codes for use in your iPhone app? Have you ever needed a list of all the Universities in the US for a form on your website?
These are the kind of lists I aim to provide.
This will not be a place to find data that changes at a high frequency. For example, while I might provide lists of companies on the NASDAQ or ISO 4217 currency codes, I would not provide actual stock quotes or exchange rates as these change all the time.
Good, that's smart of you. I highly recommend caching or downloading the data locally to your software application.
If you're building an iOS app, consider storing it locally in a PList or Realm DB. If you're building a Rails app, maybe downlaod it locally to a YAML file.
Here are some lists to get your started:
