This section demonstrates using the free tier at ExchangeRate-APIto retrieve current exchange rates from a .Net back end.

  • The API is called from the back end, so the API authentication cannot be extracted from this web page or sniffed from the browser's internet connection.
  • For the free tier the available data is only updated once per day. Paid tiers provide up to the minute data.
  • The free tier API is rate limited to 1,500 calls per month. We cache the result data to avoid calling the API unnecessarily.
  • The API returns the exchange rate from a given currency to all other currencies.
  • This application asks the API for US Dollar vs all other currencies, then uses the US Dollar rates to translate among any two currencies.

This is not particularly useful, since Google can give you this information more frequently updated. This is just a demonstration of how to call an API from the back end in .Net.
