OpenAPI Specification

The OpenAPI Specification (OAS) is a standard way for developers to describe and document how web APIs (interfaces that allow different software to communicate) work. It provides a structured, machine-readable format that details things like available endpoints, the data they accept and return, and how to authenticate. This helps developers understand, test, and maintain APIs consistently across projects, making integrations smoother, improving collaboration, and ensuring clarity without needing to read extensive code or documentation. Think of it as a blueprint that clearly outlines an API’s capabilities and how to use it.
