The Top 7 Popular Free APIs of 2021
Google recently deprecated its Google Flights API, leaving a vacuum for developers seeking to make travel apps. Surprisingly, thinking about the world’s recent travelling country, the #1 most popular API on RapidAPI is your Skyscanner API, a search engine for flight and travel information, hotels, car rentals, and much more.
- Browse Dates
- Read Quotes
- Browse Routes
- Create session
- List Places
- List markets
- Poll session
Skyscanner’s not only for travel agents or frugal travellers, either. It’s potential uses for travel suppliers themselves. They released a new feature showcasing unserved paths. This could give airlines insights into how they may continue to grow once travel recommences. Whether Skyscanner’s popularity is only aspirational considering a stir-crazy planet or forward-thinking developers seeking to benefit from the inevitable travel boom that is going to occur once lockdown ends, it is tough to say. 1 thing is for certain — almost 100 million program downloads do not lie. Programmers are probably finding Skyscanner’s API useful also!
Open Weather API
Surprisingly, the next most popular API on RapidAPI is a weather API. It is not just any weather API, however OpenWeather API is the official API of OpenWeatherMap, the company that has been providing weather channels with their information since 1979.
OpenWeather API also features an impressive collection of useful endpoints. These include:
- Present Weather Data
- Daily Forecast Weather Data
- Forecast Weather Data
- Search Weather Data
OpenWeather API’s information is gathered from over 40,000 weather stations located all around the planet. Programmers are discovering new and innovative ways to incorporate this weather data, also.
They have integrated OpenWeather to Google AdWords, for instance. The rationale they provide is that outside entertainment companies, for example, will likely be more prevalent once the weather’s fine than when it is cold and rainy. Amusement park owners may want to cut back their ad spend days when it is moist and increase it if the sun’s out.
“Soccer” is football to the rest of the world that’s not the United States. API-Football is the API that brings you more soccer-related stats than you can shake a pair of cleats at.
API-Football is acceptable for over checking the scores of your favourite teams, also. The API also provides a pre-game chance, upcoming events, team line-ups, current positions, and other stats. It is useful for everything from developing a simple tracker, for the uber-sports enthusiast, to powering sports gambling sites, to making your own fantasy football, er football, leagues. It may even be used to make predictions, suggesting API-Football may even be used for machine learning applications.
API-Football is free for up to 50 calls a day, with several additional pricing amounts beyond.
Cocktail DB API
Looking to make this Road House program you have always wanted? Just wondering what on Earth you can perform with vermouth? The astonishingly deep Cocktail DB API has you covered!
The API for the Cocktail database isn’t simply another bartender’s bible, either. Cocktail recipes also feature user’s tags and photos, so that you may search drinks for flavour, source, even the best drinks for certain meals.
The Cocktail DB API also features recipes for non-alcoholic drinks, if you would like to learn how to combine a Shirley Temple. The ability to create your own lists seals the deal, so you can create lists of all of the whiskey drinks you wish to try. Here’s your opportunity to generate drinking at home more interesting and fun before the pubs return to normalcy after the year.
To put it simply, it does exactly what its title implies — providing useful data about a state in REST format. REST Countries v1 provides a lot of possibly useful endpoints, from titles to state codes to money. While it’s a fairly easy service, REST Countries v1 is totally free, having recently been obtained by the API layer. It is already used by over 1200 customers, ranging from Spotify to holiday sites like onefinestay and Better Adventures. The indie rockers the Gorillaz have discovered a way to incorporate REST Countries v1. If it’s good enough for Noodle and 2-D, then it has to be worth a look!
And while cocktail info and soccer scores might be helpful for some fun programming missions, an API that handles cold, hard cash may be more of a cause for celebration — especially if that API provides a free tier.
The Yahoo Finance API provides more than strictly financial information and documents for people who follow economics carefully. There are many endpoints for sorting out your watchlist and portfolio, to begin with. Another endpoint features news stories about various stocks.
At the least, an individual could use the Yahoo Finance API to power a financial news program or browser, preventing you from having to navigate 100 distinct investment news resources. At best, you can use it as the backend for your own investment app or machine learning source. Obtaining real-time fiscal information is always tricky, so finding one that lets up to 500 calls per month at no cost is worthy of celebration!
URL Shortener API
A few of the APIs on our list are exciting. APIs are often an integral utility for the backend, though — basically operating within their plumbing or HVAC. The need to integrate many pre-built solutions to look after some of those mundane tasks in our development projects is 1 reason APIs are so popular and useful.
Simply send a URL into the API using a POST request for a shortened URL returned. The URL Shortener API is completely free and ready to make up to 3 requests per second.
