How to guarantee max 1 request per second if app becomes popular

[Christer]

I want to make a Wordpress plugin that displays all books on a user's "currently reading" shelf together with their progress. In the unlikely event that this becomes popular, the max requests per second may be broken, since lots of websites might use it at the same time (I'm not too concerned about the number of visitors to their blogs, that could be fixed by caching). Does this mean that I really can't do this? How can Goodreads hope for awesome apps to be developed within this limit?

There might be something fundamental I have misunderstood, please let me know if that is the case.

1. This widget already exists as created by other developers

2. Let the user get their own developer key for the plugin, have the plugin store the user's data in their own db (since OAuth is needed to identify themselves, users can save their own data to their own db) This means they do not have to call GoodReads API every time and can update their db at the push of a button from their back-end without having them route a call through you.

3. Have I misunderstood your request completely?

Thanks. I haven't found the widget you are talking about. No widgets I have seen display the reading progress ("20% complete" etc.).

I have completed development: https://wordpress.org/plugins/gr-prog...

In ended up using the "get your own API key" approach.
