indexed pages monitor

Is there some tool to monitor how many pages are indexed on Google?Any of you know if Google API offers this info?is it really all that hard to just search once a month and see?You can use a tool like digitalpoint.com's to see if you in the top 50. Of course won't tell you if you were indexed. All you really have to do is check for your site on Google every once in awhile. Just search for your url.I usually just type insite:www.url.com
