Hi Pablo,

You do not also need a ZeroBounce account, RapidAPI free version is the same as ours. The reason the free plan is limited is due to previous abuse of the free offer via RapidAPI. If you know you will need more than the free plan, feel free to enroll in a package that fits your needs. If you want more flexibility in your account then I’d recommend you sign up direclty through our website and use our API.

Hope this helps.
