OAS (OpenAPI Specification)

The OpenAPI Specification (OAS) is a standardized way to describe and document APIs (Application Programming Interfaces). Think of it as a blueprint for how software applications communicate with each other. OAS provides a clear, structured format that details the functions of an API, including what data it can send and receive. This helps developers understand how to use the API effectively, ensuring consistency and making it easier to integrate different software systems. Ultimately, OAS supports better collaboration and faster development in creating software that can interact seamlessly.
