🆚 JSON vs. OpenAPI

JSON (JavaScript Object Notation) is a lightweight, language-independent data exchange format derived from JavaScript and used to structure and transmit data between systems.

It represents data as key-value pairs and ordered arrays, supports various data types, and is widely used in web APIs, configuration files, and data storage.

OpenAPI is a specification language for defining HTTP APIs, typically written in YAML or JSON.

It enables automated generation of interactive documentation (via tools such as Swagger UI and Redoc), schema-based request and response validation, automatic creation of client SDKs and server stubs in multiple programming languages, and integration into CI/CD pipelines.
