I use Alpha Vantage, just for a personal (1 user, me) application. The service is free, you just need an API key. - https://www.alphavantage.co/

https://www.alphavantage.co/support/#api-key "While we are proud to provide free API service with no daily/weekly/monthly call limits, we recommend that API call frequency does not extend far beyond ~100 calls per minute so that we can continue to deliver the optimal server-side performance. If you would like to target a much larger API call volume, please drop us a note..."

Implementing this to replace a very low usage exchange rate form. The format of their data is... odd. E.g. -

{ "Realtime Currency Exchange Rate": { "1. From_Currency Code": "BND", "2. From_Currency Name": "Brunei Dollar", "3. To_Currency Code": "USD", "4. To_Currency Name": "United States Dollar", "5. Exchange Rate": "0.73326846", "6. Last Refreshed": "2017-11-03 17:37:12", "7. Time Zone": "UTC" } }

Why the numbers and mix of underscores and spaces in keys?

I don't know why they did that, you would need to ask them. They seem to be open to questions and suggestions. My guess is that it's historical and now it would annoy too many users to change.

I remember seeing this API from another post.... Any idea who's behind it?
