APIs are increasingly becoming new business assets for organizations andconsequently, API functionality and its pricing should be precisely defined forcustomers. Pricing is typically composed by different plans that specify arange of limitations, e.g., a Free plan allows 100 monthly requests while aGold plan has 10000 requests per month. In this context, the OpenAPISpecification (OAS) has emerged to model the functional part of an API,becoming a de facto industry standard and boosting a rich ecosystem ofvendor-neutral tools to assist API providers and consumers. In contrast, thereis no proposal for modeling API pricings (i.e. their plans and limitations) andthis lack hinders the creation of tools that can leverage this information. Todeal with this gap, this paper presents a pricing modeling framework thatincludes: (a) Pricing4APIs model, a comprehensive and rigorous model of APIpricings, along SLA4OAI, a serialization that extends OAS; (b) an operation tovalidate the description of API pricings, with a toolset (sla4oai-analyzer)that has been developed to automate this operation. Additionally, we analyzed268 real-world APIs to assess the expressiveness of our proposal and created arepresentative dataset of 54 pricing models to validate our framework.
