OpenAPI Specification (OAS)

The OpenAPI Specification (OAS) is a standard format used to describe how web APIs (application programming interfaces) work. It documents the available endpoints, methods, data formats, and responses in a clear, structured way. This helps developers understand, build, and maintain APIs efficiently, ensuring that different systems can communicate smoothly. Think of it as a blueprint or instruction manual that makes it easier for teams to collaborate, test, and integrate software services reliably. OAS promotes consistency and simplifies the development process across various platforms and applications.
