 A collective list of JSON APIs for use in web development.
 
+> While I appreciate the masses of pull requests and community involement, some PRs have been specifically to market company APIs that offer paid for solutions.

Pull requests that explicitly are marketing attempts won't be accepted, thanks for understanding! :)
