 If you need more than the 1000 API calls allowed per month, I'd suggest opting for a paid account... ScrapingAnt loves OpenSource, therefore they have decided to give all _Fredy_ users a 10% discount by using the code **FREDY10** (Disclaimer: I do not earn any money for recommending their service).

+# Analytics
+Fredy is completely free (and will always remain free). However, it would be a huge help if you’d allow me to collect some analytical data. 
+Before you freak out, let me explain...         
+If you agree, Fredy will send a ping to my Mixpanel project each time it runs.   
+The data includes: names of active adapters/providers, OS, architecture, Node version, and language. The information is entirely anonymous and helps me understand which adapters/providers are most frequently used.</p>
+**Thanks**🤘

+            <p>Fed up with popups? Yeah, me too. But this one’s important, and I promise it will only appear once ;)</p>
+            <p>Fredy is completely free (and will always remain free). If you’d like, you can support me by donating
+                through my GitHub, but there’s absolutely no obligation to do so.</p>
+            <p>However, it would be a huge
+                help if you’d allow me to collect some analytical data. Wait, before you click "no", let me explain. If
+                you
+                agree, Fredy will send a ping to my Mixpanel project each time it runs.</p>
+            <p>The data includes: names of
+                active adapters/providers, OS, architecture, Node version, and language. The information is entirely
+                anonymous and helps me understand which adapters/providers are most frequently used.</p>
+            <p>Thanks🤘</p>
