Free public APIs, like special tools for computer programs, are very important for lots of developers. They give a lot of information and features that can be used to make many different apps, like weather apps, news apps, and even tools for other developers.

Free Public API’s for developers

API or Application Programming Interface is the connecting and communicating bridge between the frontend technology present on the client side and the database working at the backend. It is a messenger that helps us to deliver our request to the resource provider and then delivers the response to the user seamlessly.

What are Public API’s?

Public API is one of the types of API that is publicly available to everyone without any pre-requisite access. It is freely available to third-party developers in building software applications.

Public APIs are free and open source and can be implemented in a project using registered API keys unique to every public API. A third-party application like POSTMAN uses an API key to load a response from the server and request it to the front-end user. Public APIs are the best type of API for learning enthusiasts and developers to learn and integrate different tech stacks together.

Types of Public API

The Public API’s are classified into 4 types:

  3. GraphQL
  4. Webhooks

There are a lot of benefits of working with public API for the developers:

  • Public API minimizes the workload of developers in finding the extensive dataset for the software application by providing comprehensive data in the form of API to speed up the development process.
  • Public API creates smooth integration and communication between front front-end applications and back-end services provided by the server.
  • Developers can solely focus on the functionalities and features of software applications without worrying about the correctness, redundancy or completeness of data.

Must Read:


Public APIs are the access key to pre-built functionality and services of data retrieval in JSON format allowing applications to focus more on the functionality of the software application by delegating all data request and response operations to public API without thinking of building a core database server from scratch. The project requirements and developer learning graph decide which API to choose from in building a whole software application that could bring light to your coding practices and resume template.
