In the software development world, APIs (Application Programming Interfaces) provide us convenience in many ways. By using APIs, we can obtain the data we need in our projects with a single HTTP call. In addition, we can provide data to external systems with APIs. Today, there are many paid and free public APIs, especially in API marketplaces, that can be used in our projects. In particular, free APIs have a very important place for us.
Free public APIs can significantly increase the capabilities of our projects. The fact that there is no cost allows us to use these resources in software development processes, mostly in test environments. In this article, we will introduce you to 8 free and very efficient APIs that developers frequently use in software development processes.
The ipstack API
The ipstack API is a geolocation API. It provides its users with geolocation information corresponding to their IP address. The geolocation information it provides is quite detailed. Provides information such as continent name, currency, time zone, continent code, and more. Free for up to 100 requests per month.
Users often use this API to provide localization services to their visitors. For example, many websites providing international services change the language of the website according to the location of the user.
The sample integration code of this API for the Python programming language is as follows:
| import requests url = “https://ift.tt/YmkdbMi; payload={} header = {} response = requests.request(“GET”, url, headers=headers, data=payload) print(response.text) |
OpenWeatherMap API
OpenWeatherMap API is a weather API that provides a very comprehensive weather service to its users. This API provides weather data for more than 200,000 locations around the world. Apart from current weather information, it also provides information such as hourly forecasts, daily forecasts, climatic forecasts, and historical weather.
This API is used in almost every business and project. Today, weather panels on many television channels and location-based weather pages on news sites provide data from this API.
The sample integration code of this API for the Python programming language is as follows:
| import requests url = “https://ift.tt/t3lFLw0 key}” payload={} header = {} response = requests.request(“GET”, url, headers=headers, data=payload) print(response.text) |
REST Countries API
REST Countries API is a free API that provides information about world countries. This API gives users access to a variety of data such as flags, capitals, populations, currencies, and languages of different countries. The API returns data in JSON format.

The sample integration code of this API for the Python programming language is as follows:
| import requests url = “https://ift.tt/bwM3RkA; payload={} header = {} response = requests.request(“GET”, url, headers=headers, data=payload) print(response.text) |
Zenserp API
Zenserp API is a web scraping API that provides web scraping services to its users. The specialization of this API is SERP data. Zenserp API provides SERP data for popular browsers such as Yandex, Google, Bing, and DuckDuckGo very quickly. In addition, it provides its users with data that is difficult to scrape, such as Reverse Google Images and YouTube Search data.
Zenserp API is frequently used in companies that develop strategies in the field of SEO today. It is also used in many artificial intelligence projects to obtain up-to-date data.
The sample integration code of this API for the Python programming language is as follows:
| import requests headers = { “apikey”: “YOUR-APIKEY”} param = ( (“q”,“Pied Piper”), (“location”,“New York,New York,United States”), ); response = requests.get(‘https://ift.tt/WYLM6e4;, headers=headers, params=params); print(response.text) |
Unsplash API
Unsplash API is a prominent API among image APIs that provide high-quality stock photos to its users. The Unsplash API is used for users to programmatically access photos on the Unsplash platform. This API provides users with listing photos, getting a photo, getting a random photo, getting a photo’s statistics, tracking a photo download, and many more endpoints.
The Unsplash API provides developers with high-quality visual content that they can use in many projects. For example, websites, blogs, or design tools can get visual content using the Unsplash API.
The sample integration code of this API for the Python programming language is as follows:
| import requests url = “https://ift.tt/8LSEKxX; payload={} header = {} response = requests.request(“GET”, url, headers=headers, data=payload) print(response.text) |
The numverify API
The numverify API is a number validation and information lookup API. This API supports phone numbers in 232 countries. It obtains the information it provides to its users from the official institutions of the countries.
This API is used for phone number verification steps in banks and e-commerce applications. It is preferred in the application registration process or payment process as it increases security.
The sample integration code of this API for the Python programming language is as follows:
| import requests url = “https://ift.tt/ZHmIjXx; payload={} header = {} response = requests.request(“GET”, url, headers=headers, data=payload) print(response.text) |
JSONPlaceholder API
The JSONPlaceholder API is one of the free public APIs that provide developers with test data in JSON format. With this API, developers can test with HTTP GET, POST, PUT, and DELETE methods. Additionally, this API provides a lot of resources to developers with endpoints such as /comments, /users, /albums, and /photos.
The JSONPlaceholder API is a useful tool for developers to test API requests, build prototypes or try out some simple scenarios. By using these APIs in their projects, developers easily increase the efficiency of integration and testing processes.
| The sample integration code of this API for the Python programming language is as follows: import requests url = “https://ift.tt/DjJ0fGu; payload={} header = {} response = requests.request(“GET”, url, headers=headers, data=payload) print(response.text) |
