Free APIs (often referred to as public or open APIs) are APIs that developers can use at no cost to them (like many of the APIs listed in this collection). Unlike freemium APIs, free APIs on RapidAPI no credit card input.

Freemium Model: Under this model, the basic API functionality is offered for free, which helps attract developers to the platform. As the users' needs increase, they can opt for premium, paid features, like higher rate limits or access to advanced services.
