Google checks your IP address and blocks it if you have too many requests in some amount of time.

If you're planning on having many requests to Google in a short amount of time, they'll usually win and block you with a captcha based on your IP.

So you can either get access to multiple IPs to do what you're doing, or better yet throttle your requests so you don't run afoul of them.
