API monetisation is becoming a sought-after feature in the API Management space. Most companies want to charge for API usage rather than simply charging for use. There are a number of different ways that this can be achieved. Tiered pricing and Freemium models are two models that can be used to monetise API usage. These models require integrating an API manager with a billing and collection engine such as Stripe. API providers would also have to create accounts in Stripe and link it with the platform account using Stripe Connect.
