The public API concept enables businesses and developers to access or produce data easily. A few examples are:

  • Twitter API for Twitter data.
  • Geolocation API for geolocation data.
  • Scraping API for results of search engines.

Today, it is possible to find public APIs in multiple categories. Public APIs are divided into paid and free APIs.

Today, although GraphQL API and gRPC technologies are on the agenda, public REST APIs are more common. Many businesses prefer and use paid or free REST APIs according to their needs and requirements. In this article, we’ll go over the pros and cons of paid and free APIs, and then we’ll get to know the most popular API provider today.

Exploring the Pros and Cons of Free and Paid APIs

These APIs, which are frequently used by both businesses and developers, have many pros and cons compared to each other. When choosing an API, choosing one of these APIs is more appropriate according to the project’s needs.

Free APIs


No cost: The biggest benefit of the free API to developers and businesses is that it doesn’t cost anything. It is used for any project that has budget constraints and needs fake data.

Easy access: These APIs are publicly available. Developers can start using it quickly by integrating it into any programming language.

Wide availability: It is a developer-friendly API. It is possible to find hundreds of free APIs in multiple categories, offering various uses.

Opportunity to learn and test: Free APIs allow developers to test APIs. This way, testing and learning this API before purchasing it is possible.


Support: Free APIs may not have the same level of support as any paid API. This may reduce the chance of getting help in case of correctness, security, or error of the provided data.

Usage limits: Limitations can be made on API requests made to free APIs. Especially in free APIs offered as free trail, this limit is determined monthly.

Paid APIs


More functionality: Paid APIs are often more advanced in content and scope than free APIs. Paid APIs come with more features and functionality.

Better support and maintenance: Paid API providers usually provide support for the API they provide. There is a support team that can quickly help with any issues.

SLA (Service Level Agreement): Paid APIs typically provide a service level agreement that guarantees a certain amount of uptime and support. In this way, these APIs provide trust for critical applications.


Cost: One of the biggest is that paid APIs are not for every budget. It causes an increase in costs, especially in many small or medium-sized projects.

Additional integration challenges: Some of the paid APIs come with additional complexity or requirements for integration. This increases the cost spent in the integration process.
