Hey Deepak,
Thanks for taking interest in Medium API.
Yes, it is totally safe to subscribe to Medium API on RapidAPI. Over half a million developers use RapidAPI and it is a well-trusted platform.
Medium API has 4 plans - 1 free & 3 paid. Paid plans have hard limit on the number of API calls, whereas free plan has a soft limit on the number of API calls.
Check out: http://hub.mediumapi.com/pricing
In the free tier (BASIC plan), you'll get 150 calls per month which are enough to try and test the API. If your requirement is high, I'll recommend you switch to a paid plan (like PRO, ULTRA or MEGA).
⚠️ Remember, there is an overage fee in the free plan ($0.04 per extra call), so please be careful and keep a count of the API calls in the free plan.
If you're developing a large-scale production application, email me at "nishu@mediumapi.com" to discuss customizations and business discount.
Have a great day!
Regards
Nishu
