API Economy and Beyond

Today’s digital economy is shifting toward dependence on microservices — self-contained and reusable software components — working in coordination to compose the applications we use. Communication between microservices happens through the API. Using APIs (which are like pieces of software that let applications communicate with each other) is how microservices expose their functionalities and allow access to their services and their data.

The API economy refers to the controlled exchange of digital data and services through APIs. The API economy is the combined value exchange between providers of APIs and consumers of them — both of which exist within a organization and beyond. The API economy is not a technical concept, nor is it a financial model. Instead, it reflects an ecosystem of mutually beneficial exchange of data and digital services.

Let us look at some tools for creating the API’s with documentation.

Best API documentation tools you need

You could document APIs manually or use a documentation tool for that. API has specifications for each type of API. For REST APIs, there is the Open API Specification, and for GraphQL APIs, there is a Schema Definition Language.

Creating API documentation manually is tedious. It is better to auto-generate your API documents using API document tools. These API tools could design your documentation and make it more presentable and appealing to your readers. There are so many tools out there for API documentation. This article aims to highlight some of the best API documentation tools.

Why you need API documentation tools

API documentation tools aim to speed up the documentation process. They can generate documentation from an API, making it faster for you to document your APIs efficiently and keep up with changes in the APIs. These tools help to organise and structure documentation, making it easier for writers to write their documentation clearly and logically.

Every API document needs to be up-to-date so these tools provide features that record and update changes and also promote collaboration. They provide design features to style the user interface of the documentation. Which improves the user experience for developers reading the documents.

API documentation tools can provide examples or use cases based on real-life scenarios of the API to help you write better. Generally, these tools make it easier for writers to create organised documentation. They also make it easier for developers, product managers, and other team members to use APIs effectively.

Best API documentation tools

The best API documentation tools that have brilliant uses and benefits are:

  • Swagger

  • Postman

  • Readme

  • Stoplight

  • Redocly

Let us look one by one


Swagger has so many features that make API documentation seamless, which is why developers and writers love it.

It generates documentation automatically from OpenAPI definitions. It also designs your documentation with an amazing interface to reveal an aesthetic appeal using SwaggerUI.

Swagger provides versioning, which is a great way to maintain and easily update your documentation. With Swagger, you can run tests and deploy your documentation with ease.


Postman is a great API management tool that not only tests APIs but also generates documentation from APIs.

With Postman, you can generate content from your API, and it updates your documentation whenever you make changes to your API. Postman promotes collaboration among teams by making it easy for you to share documentation.


Stoplight is an API documentation tool that has beautiful design features. It is tagged “design-first” because it auto-generates your documentation using great design themes. Stoplight hosts your documentation on its server, which reduces the hassle of hosting on a different server. It also provides a style guide editor that lets you document your APIs efficiently.

Stoplight has consoles you could use to preview your documentation, although you cannot monitor your documentation’s performance.


Redocly is an API documentation tool that integrates with git for Docs-as-Code. It also lets you preview your changes before you merge them. With Redocly, you could easily set up your API documentation pipeline and deploy it to any platform of your choice. It is designed for both developers and writers.

It integrates with CI tools, making it possible for you to test and update your changes in a secure environment. Although using Redocly requires technical knowledge, it has well-detailed documentation that serves as a guide.

Document360 API documentation

Document360 is a knowledge management software for documentation. Some of its features include creating internal and external knowledge bases, API documentation, standard operating procedures, and so on. Its API documentation feature lets you create standard API documentation with a test console to run your API requests and examine responses.

You can import API definition files into it and begin documentation. It provides an editor to view your live edits to your documentation. It also syncs your updates, keeping your docs up-to-date.

You can also view your logs to monitor changes you have made and be aware of any errors.

Factors to consider in the quest for API documentation tools

Some factors to consider in finding API documentation tools are:

Seamless Integration

Consider tools that integrate easily with other tools like version control systems, continuous integration systems, and so on.

Ease of use and customization

Choose tools that have a great user experience. Tools that accelerate your work rate and that you could easily customise to your taste.


Always consider tools that provide resources on troubleshooting and, if possible, tools with a great developer community. That way, you can always get help from the community when you need it. Companies usually place their customer service behind a paywall; if you can get it, then that would be helpful too.


Security is important in API management. When working with APIs, look for tools that focus on and enforce security to avoid unwarranted attacks.


Choose tools that can offer you what you need on an affordable budget. These tools normally offer free and paid plans. It is up to you to select which of the plans would be realistic for you and within your budget.

By considering these factors, you can choose an API documentation tool that fits your needs and helps you create comprehensive and accessible documentation for your APIs.
