FAQs

What are the three most common types of APIs?

REST, RPC, and SOAP represent the three primary methods or designs for APIs used in modern software development.

• REST (Representational State Transfer) is widely favored for its simplicity and compatibility with the web. It utilizes standard HTTP methods like GET, POST, PUT, and DELETE to perform operations.
• RPC (Remote Procedure Call) focuses on actions, enabling a client to execute code on a server as if it were a local procedure. It often uses protocols like JSON-RPC or XML-RPC.
• SOAP (Simple Object Access Protocol), though more complex, provides a high level of standardization and security, using XML to ensure that messages maintain their integrity and confidentiality across diverse networks

What is an API, and why are they essential for business?

An Application Programming Interface (API) lets software applications communicate and interact with each other. They are essential for businesses because they offer automation, streamline workflows, and enhance user experiences.

Where can I find free APIs?

You can find free APIs in online marketplaces such as APILayer. Explore the platform, and you will get a curated collection of APIs for geolocation, currency conversion, weather data, and more. 

Can you expect scalability as your business grows when using these APIs?

The scalability of APIs depends on the architecture, Infrastructure, and design principles employed by the API provider and your business. While some free APIs accommodate growing demand and traffic, others have limitations under heavy loads.

Is API the same as JSON?

First and foremost, JSON is a data format that programs and online services use to communicate with one another, not an API. There are several web services, but REST and SOAP are the most used. You may connect with and communicate with distant devices via web services.
