Which Google API do you use to creat a rank checking tool?

I'm just saying its frown upon, not down right illegal. As i said, there are ways around it.

I happen to know the RankTracker does use the Google API, after a few uses it requires manual input for passing the prove your human captcha.

As for SEOmoz, its a good question, I have no idea how SEOmoz track SERPs, probably a trade secret though!

We did some tests with the Google API, but weren't really satisfied with it ... you might want to try scraping results "directly" via a series of different proxies and see if you get better results this way.

Google Webmaster Tools provides rankings, though averaged they can be tweaked to a near accurate value. Their API does not support rankings at this stage, but if enough people kick and scream about it - they may! hint hint

Which API do you use though? The SOAP is not around anymore and this page http://code.google.com/more/ doesn't have anything that jumps out at me

I need to create somethng that works on the fly, without any analytics or webmaster account

To my knowledge what you seek does not exist. If you do dig it up please share with the rest of us!

As gmellak says, you may want to try the scrape approach. However, Its a dirty approach and if you submit too many requests you will get Captchas.

Has anyone used authoritylabs? They seem to do a decent job...

Traffic Travis has a nice  and easy to use free windows app that does what you want (for low volumes). http://www.traffictravis.com/  you'd be better off using a proxy service with it though.
