Our API allows you to query for Google PageRank for up to 1,000 pages per day, for free!
Using our API is simple. Just make a standard HTTP request to this page:
http://webinfodb.net/a/pr.php?url=<URL-HERE>
For example, to get the PageRank for 'webinfodb.net', load:
http://webinfodb.net/a/pr.php?url=webinfodb.net
If a PageRank was found, the response will be a single number, such as '2'. If there was an error, you will get an 'E:<ERROR>' response, where <ERROR> is replaced with the error.
If the limit is exceeded, you will get the following response:
E:Limit exceeded
You may recieve E:Too Busy. Try again in a few minutes. as a response (HTTP Status 503). In most cases, a Retry-After HTTP header is also sent. You MUST obey this header and not make any further requests until the time specified.
We have made available a PHP class, a demonstration script and the PageRank icons in this downloadable package:

Make more than 1,000 requests per day!
If you intend not to exceed the 1,000 requests per day, per IP limit, then you do NOT need an account. Otherwise, you will need to sign-up and obtain an API key:
