URL Profiler can access the uClassify API to extract content analysis data about URLs:
Sign up for your uClassify account on this page.
Once you’ve signed up you will see your allowance – the free account will be sufficient for most uses.
Then navigate to their API Keys page and copy the ‘Read’ API key, which you need to paste into URL Profiler. Click ‘Accounts’ in the top navigation and then choose the ‘uClassify’ tab, then paste your API Key into the box.
