Your API not listed?

Just let us know via or Twitter what vendor, api and version is missing (please add information where the information can be found, if possible).

What and Why

Problem: You use an versioned API like Google Adwords. These APIs have a deprecation date, but you miss it because there's no meta-field in the API that provides you the deprecation date. You miss the deprecation date and your app fails. Your app reputation drops, customers are unhappy. You update in panic and hope that I will work out. And you promise to yourself that it will never happen again.

Solution: provides a single source for deprecation dates for all of your APIs (tell us when your API is missing -

Howto: Check out our examples or write your own pull script based on the documentation.
