What exactly is open API?

An open API, also called public API, is an application programming interface made publicly available to software developers. Open APIs are published on the internet and shared freely, allowing the owner of a network-accessible service to give a universal access to consumers.

What is open API vs REST API?

The OpenAPI Specification (OAS) defines a standard, programming language-agnostic interface description for REST APIs, which allows both humans and computers to discover and understand the capabilities of a service without requiring access to source code, additional documentation, or inspection of network traffic.

What is closed API?

When an API is not open — meaning, released publicly — it’s called a “closed API” or an “enterprise API.” Sometimes, developers also refer to “dark APIs.” Whatever it’s called, the API will not be made publicly available and will be tightly controlled.

Start Using an API

  1. Most APIs require an API key.
  2. The easiest way to start using an API is by finding an HTTP client online, like REST-Client, Postman, or Paw.
  3. The next best way to pull data from an API is by building a URL from existing API documentation.

Is OpenAPI good?

OpenAPI definitions can play a part in every step of the API development lifecycle. Consider using them from the ground up when designing new APIs to get the most benefits, but even adding an OpenAPI definition later on can still be helpful for quality control and for attracting developers to your API.
