It seems like it sometimes works on ecosia, but not for everyone. Ddg also seems to have a similar issue, where it sometimes works depending on location (?). I guess even if it is not related to api pricing, it still shows that search engines that depend on reselling or vendoring an API aren't much of an alternative to the big guys (though ecosia is awesome, and it doesn't pretend to compete on the search offering itself ).
And hopefully I'm totally wrong about the whole situation being related to pricing!
