If you looking to add some serious oomph to your next programming project, I've compiled a list of 16 free APIs that can help you build amazing things, without rubbing the bank.
Let's dive in…
1. Unsplash API
If you’re tired of those generic, low-quality, full of watermark stock photos, Unsplash API is here to save you. With this API, you can access a treasure trove of high-quality, free stock photos.
Imagine building a blog post generator that automatically pulls relevant images, or a group chat bot that adds a visual touch to your conversations. The possibilities are endless, just think about it.
2. YouTube API
Using this API you can take a full control over YouTube. You can use this incredible API to dynamically change thumbnails, titles, and even perform A/B testing to see which title or thumbnail get the most clicks.
3. Pantry
This API allows you to store up to 100MB of JSON data, complete with a user-friendly CRUD interface. Think of it as a lightweight alternative to traditional databases, perfect for small-scale projects. If you don’t know database, well don’t. This API is way more simple database to integrate your project to.
Similar to TinyDB in Python if you’ve used it before.
4. Clearbit
Ever needed to display a company logo in your app? Clearbit API comes to the rescue!
With a simple HTTP request, you can fetch the logo for any company, adding a touch of professionalism to your projects.
It’s very useful — if you care about company’s logo actually.
5. Waifu API
For all you anime enthusiasts, the Waifu API is a must-try. This API lets you create your own anime wife, complete with a variety of features. My favorite is the /uwuify endpoint, which transforms your text into the cutest, most adorable form possible.
6. The Internet Game Database (IGD) API
If you’re a gamer-programmer, the IGD API, powered by Twitch, is a goldmine of information about any game.
Search for game versions, genres, covers, images, and more. Build your own game database or create a unique gaming experience with the power of this API.
7. Discord API
The Discord API allows you to build custom bots that can play games, interact with your community, and much more.
Think of it as a way to bring your server to life with the power of this API.
8. World News API
If need up-to-date world news for your application, the World News API provides a free tier, but be aware of the daily call limit.
If you're building something that requires frequent news updates, their paid plans are still worth it.
9. Random Data API
Testing an app? You'll need some fake data initially. The Random Data API provides a wealth of data models, perfect for populating your application with realistic information.
What I love about this API is that they require no API key!
10. FX Rates API
Dealing with foreign exchange rates can be a headache. The FX Rates API eliminates the stress. Get real-time exchange rates and even historical data with their free tier.
Perfect for any application that involves financial transactions.
11. Google Docs API
Did you know you can connect to Google Docs with an API? Use it to access data from your documents, create add-ons, or integrate with other services.
It seemed unbelievable at first when I heard Google Docs has API. But here you go.
12. ILovePDF API
I bet we all love PDFs. The ILovePDF API lets you love PDFs even more.
Extract text, edit, remove passwords, compress, convert, and more. This API is a must-have for any application that involves PDF manipulation.
13. CloudConverter API
Need to convert files between different formats? The CloudConverter API makes it a breeze.
Get 25 free conversions per day, perfect for small-scale projects. But if the conversion is only between two specific file types, I’d recommend automating it with Python, no APIs needed.
14. Free Dictionary API
This API doesn't require an API key and is powered by donations — props to them.
You can build a simple dictionary app or integrate it into your existing projects to add a touch of vocabulary magic or if you highlight a word, it’ll give you the definition.
15. Spotify API
The Spotify API lets you access a wealth of music data, from artists and songs to listening history to the pennies that they pay artists every year.
Build a music recommendation engine, create a personalized playlist generator, or fetch your recently listened song.
16. Open Food Facts API
Ever wondered what's in your food? The Open Food Facts API has got you covered.
Enter a barcode number, and it will provide detailed information about the product, including ingredients, nutritional values, and more.
Perfect for building a food tracking app or a nutritional information tool.
