The "API loaded" lights up green in the test tool if you include the API from the URL like described in the documentation. Since you can't define remote dependencies the plugin uses a local copy of the API js file.
Feel free to replace the script reference in the index.html file of the exported project.
However skyhunter93 submitted successfully even though his project worked with a local script, so it might not be necessary.

You probably don't want to request an ad right on startup. That would mean the user instantly saw an ad after loading the game.
I'm also not sure it will work properly if you don't allow for a little time between loading the API and requesting an ad.
Remember, you load the API only once and you request an ad whenever you want to actually display one. For example when a level ends.
Could be that the sub-domain redirecting you're doing is causing problems with the test tool. I would definitely try to use a direct URL to compare.
