In this post, I will show you how to build an income stream online with a $0 Budget.
We will build an API and Sell it without writing any line of code.
What is an API?
API Stands for Application Programming Interface (No need to memorize or know this 😅).
Let’s make things as simple as possible.
API allows programmers and developers to interact with a specific platform or access data and tools directly from their custom application (code).
Suppose a programmer wants to develop social media management software like Buffer or Hootsuite.
In that case, he will need access to Facebook, Twitter, Pinterest, and other social platforms directly from his code so he can publish, schedule, access analytics, and do other stuff from his own application.
But this is not possible by default because if you want to post on social platforms, you must use their interface. So what to do?
How do social media management tools access platforms like Facebook and Twitter?
Here, the API solves this issue and acts as a gateway or a broker between the programmer and the target platform.
For example, Facebook allows programmers to access Facebook through Facebook API, just like Twitter, Pinterest, Google, and many other platforms.
Another Example of APIs is allowing programmers to access data on a specific server or database.
We can’t give programmers public access to our servers and databases. So we create an API that can manage and handle this securely.
And if you like reading technical definitions, here we are:
API stands for Application Programming Interface. It is a set of rules and protocols for accessing a web-based software application or web tool. Simply, it allows communication between different software systems and enables them to exchange data.
I think that’s enough; hopefully, you’ve grasped the concept of APIs.
The API Business Blueprint
Let’s Understand The Idea behind making money with APIs.
How can we, as simple human beings, establish an online income stream with APIs?
We mainly have ways to make money with APIs:
- Build and Sell APIs
- Consume an API and Build Your own tool or SAAS.
1. Build and Sell APIs.
And this is what this post is all about.
The idea is simple. You will find an idea that can solve a specific problem for certain people.
Then, You will build and Host the API. After that, you will List the API on Marketplaces like RapidAPI. Then, you will promote the API. And you will establish a recurring monthly income.
The Idea may seem complicated, but it is not. Believe it or not, you can do this every month!
2. Develop a tool, app, or SAAS based on APIs.
The second method is to build a tool’s website based on APIs.
This website can be a free tool or a SAAS subscription-based website. Or even a mobile app!
I do this with PromoterKit and built many tools based on third-party APIs.
For example, the Hashtag Generator Tool is built on top of the Hashtagy API.
This method is out of the scope of this post.
The use of APIs speeds up the development time and process. It also simplifies the work of developers since they can use ready-made solutions. There is no need to reinvent the wheel and spend time building something already existing.
Let’s take as an example Google Maps, which developers can embed in applications and websites. Rather than building a map each time you need one, you can simply use the one provided by Google. Can you see how much time and resources you save this way?
Thus, by using APIs, you can save time and resources and also monetize your work!
How to Build APIs?
Building APis can be as easy as dragging and dropping some boxes in no-code tools. And it can be complex as developing enterprise programs.
In short, We can build APIs using one of the following methods:
- Develop yourself from scratch if you are a programmer (or if you are willing to be one)
- Hire a Developer to do the job for you.
- Use No-Code tools to build an API.
- Use AI To Generate an API.
- Use a mix of the above methods 🙂
In this post, we will go with no-code tools
Build an API with a No-code tool
Here is the cool part!
Usually, to develop and build an api, we use a specific programming language like Python, C#, Java, JS…
And we write the code to build our target API. Today, we don’t want to write code! And I am not talking about prompting ChatGPT to write for you, NO!
We want to build an API without code! I will use a no-code tool called Xano.
APIs are like any business. You need to find a profitable idea and build an API around it. Let me share with you some ideas fast:
- Build an API based on other APIs, for example, I used the YouTube API to build Popular Videos Explorer API, you can find the tool online here to test.
- Combine Multiple APIs together to achieve a specific result, for example, I used multiple APIs to build the Questions Explorer API, and you check the UI also here.
- Build APIs that are based on Data. For example, I collected millions of Keywords with search metrics and turned the data into a CPC explorer tool. You can check here.
- You can build an API on top of trends like AI, ChatGPT, and so on. I built multiple tools and APIs like this, like the Free AI Image Generator and PrompoterKit’s AI Tools. And others.
Note: When I say, I built a tool, it means it is built on top of an API the I built 🙂
Today, to keep things simple and help you practice this, I will go with the third approach, which is building an API based on data.
I will give you the data so that you can follow up with me.
Our API Project
We have a database of email subject lines containing two fields (Subject lines and scores)
We will turn this into an API where developers and users can search for Subject line ideas and check their scores.
I created a 5 minutes video to show you how to implement the API step by step. I really hope you follow up and try it yourself. Everything is free, try and learn!
Here is the video:
Turn the API into an Income Stream
Now, after you create the API, you need to Host it online with services like Heruko, Digital Ocean, or any service you want (you can start for free).
After that, you will List the API on Marketplaces like RapidAPI. Then, you will promote the API. And you will establish a recurring monthly income. (promoting APIs will be a dedicated guide soon, keep an eye on my updates here)
This is what I did with The Domain Authority API that I am selling on RapidAPI Marketplace.
Do not fear failure but rather fear not trying.
If you have any questions, I am here to help; waiting for you in the comments.
Please i need video on how to collect data on the internet
Thanks for the knowledge share. What alternatives for I have if PayPal is not supported in my country (because as far as I am aware, RapidAPI supports only PayPal to cash out).
Check other marketplaces
Thanks, this article is very nice. I really enjoy reading this article.
I stumbled upon your blog post and I must say, it’s an absolute gem! Not only did it offer valuable insights into creating APIs without any coding, but it also motivated me to explore the possibilities of no-code development. Allow me to express my deepest appreciation for your outstanding content!
Very nice article. Thanks for this amazing learning
Where do I upload attachments?
Thanks for this article, I really enjoy this article. And thanks for the information
Thank you Raj
