How To Build and Sell an API Without Coding (For Free)

Let’s Use No-Code Tools To Sell an API and Build an Income Stream

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?

I think, since you click on this post, you probably know what an API is if that is the case, you can skip this part. But in case you don’t. here we are:

API allows programmers to interact with a specific platform from their custom application (code).

For example, suppose a programmer wants to develop social media management software like Buffer or Hootsuite. In that case, he will need to access Facebook, Twitter, Pinterest, and other platforms directly from his code to be able to publish, schedule, read analytics, and do other stuff.

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??

Here, the API solves this issue and acts as a gateway 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.

I think that’s enough; hopefully, you’ve grasped the concept of APIs.

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.

💡 The Idea

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:

1. 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.
2. 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.
3. 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.
4. 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. you can download the database for free here.

I created a 6-minute 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

We mainly have ways to make money with APIs:

1. Build and Sell APIs
2. Consume an API and Build Your own tool or SAAS.

Today we are focusing on the first method, so we want to publish and sell it online.

So to do that, You will Host the API on services like Heruko, and Digital Ocean (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.

This is what I did exactly with The Domain Authority API that I am selling on RapidAPI Marketplace.
