The short answer is NO, you do not need to subscribe to any additional service in order to use URL Profiler.

There are loads of really useful functions that don't require API keys or are completely free to use.

For clarity, I'll run through each of the 3rd party integrations we offer, and whether or not you need to pay to use them:

Majestic

URL Profiler has an in-built free API that you can use without even entering an API key (up to 500 requests per day). If you do have a paid subscription you can enter your API key and get even more data!

Mozscape

URL Profiler has an in-built free API that you can use without even entering an API key (up to 500 requests per day). If you need more data, Moz also have a free API you can use to get their data - details on getting set up on our user guide.

If you subscribe to one of their paid API plans, you can get the data a lot quicker.

Ahrefs

Ahrefs they have no free API options currently, so you will have to subscribe to one of their plans in order to use their data.

Copyscape

You do need to pay, and it is very expensive. However we built our own duplicate content checker which works out to be much more cost effective and accurate than Copyscape anyway.

SEMrush

SEMrush they have no free API options currently, so you will have to subscribe to one of their plans in order to use their data.

Only the ‘Business’ subscription now offers API access (you can also sign up for a ‘Custom Plan‘ to include API access).

Alexa & Whois Data

You do need to pay to get this data, provided through an API called 'My Addr', which is dirt cheap (here is a step-by-step guide to getting set up).

Google Analytics

Completely free, just login and get going.

Google Search Analytics

Completely free, just login and get going.

Google PageSpeed  & Mobile Friendly

Completely free, however you need to sign up for an API key.

Google Malware Checks

uClassify, free API

Then there are a load of functions which we built ourselves or use free public APIs - social share counts, social account link scraping, email address scraping, HTTP status, indexation checks, loads of readability checks, link analysis with very robust link classification, and plenty more.
