Ensuring business continuity through upgrade keys and subscription

This article is based on a post from now discontinued support forum. It is still available here.

Mondor’s Currency Rates Web API has one unique feature – rechargeable access keys. You can buy them as any other keys, and sometimes they are cheaper, but they can be used for a sole purpose of recharging another key of the same type.

Imagine, that you have successfully applied our currency conversion service in your application. Now your application is installed in many different places and your users expect it to work 24/7. Redeploying application just because you have to replace API key is a bad option.

Recharge key allows you to prolong the life of existing key without touching your application. And here is how it works:


Backup Servers

To minimize the downtime we’ve established a backup server for the currency rates API. Should you experience any problems with the main URL, use this server name instead: v2.mondor.org.

Please note, that backup servers will only be available for keys with expiration date, such as Monthly, Annual, 6 months and Quarter. Keys with the maximum number of API calls or limited by maximum number of API calls per day, should only be served by the main service.

Web API access

Finally, we’ve enabled the Web API access, which could be used to simplify access to our currency rates API service from JavaScript or anything else.

Consider the following URL:


This simple URL contains 6 parts:

  1. Path to conversion service, which is mondor.org/convert
  2. Your access key
  3. Base currency
  4. Target currency
  5. Amount of base currency to convert (OPTIONAL, default is 1)
  6. Date of conversion rate (OPTIONAL, default is today, format is DDMMYYYY)

You can also use the HTTPS instead of HTTP, so that your connection would be protected by 2048 bit SSL. In that case your query would look like


(in this example we are querying the current rate for 1 unit of EUR).
