find and use the best free public APIs

Have you ever wondered why businesses today can emerge in such a short time? Many startups and applications can be made available to users in just days. The main reason behind this is that the data is ready. A ready-to-use and up-to-date data set save businesses years. Businesses usually obtain ready-made data from the API provider, which also includes free public APIs.

An API provider can be evaluated under many headings today, like the company website and open-source projects. However, when we want to see both paid and free APIs together, the concept of an API marketplace appears. Let’s take a closer look at the API marketplace concept and get to know the most popular API marketplace today.

What is the API Marketplace?

An API marketplace is a web platform where developers and businesses can find and use APIs (Application Programming Interface). It provides both paid and free open APIs. The API marketplace serves as a central hub for discovering and accessing APIs from a variety of providers.

In addition, an API marketplace can have multiple categories of open APIs. Like Food APIs for food products, a social media API for social media posts, a weather API for weather information, and a news API for news sources, etc. API marketplaces often contain API documentation for the APIs they provide. This shortens the integration process considerably.
