What does API key and "calls" mean?

I received an email from wunderground as follows:

"Hello,

Your wunderground API key exceeded its allotted usage today by making 11 calls within a minute but the limit is 10.

We used one of your raindrops instead of disabling the key for the remainder of the day. You now have 3 remaining raindrops.

We check usage for 24-hour periods based on U.S. Eastern Time."

I don't quite understand what does this email mean. I installed a plugin called "GoGadget Weather and Weatherforecast Widget" on my blog so my audience have access to the weather on my site.

I don't quite understand the API key and the calls. Please kindly advise. Thank you.

The API key is a unique sequence of characters (ex. b34dxa4r52cs) assigned to your username which gives you access to wunderground's API. A "call" is a request you make to wunderground's API to retrieve data. If you are using the free membership there is a limit of 10 "calls" (requests) that you can make per minute. Thus, if you surpass this limit, as shown in the email you received, wunderground will send you this email. If your raindrop count reaches 0 your API key will be disabled (you won't have access to the API if the key is disabled) for the rest of the day.

It seems that the plugin you installed consumes data from wunderground's API with using a free membership key that is limited to 10 calls per minute.
