what it is, what it is for and how you can get one to use in your projects

Let’s explain to you what it is and how to get a Gemini APIthe artificial intelligence from Google. It is a kind of essential key or bridge if you want to develop an app or create a workflow that includes artificial intelligence, and in which you decide that this AI is Gemini.

We are going to start this article by explaining what the Gemini API is and what it is for, trying to help anyone understand the concept. And then, we’ll tell you step by step how to get your Gemini API to use in your projects.

What is the Gemini API and what is it for?

Gemini is the name of Google’s artificial intelligence chat, but it is also the name of the AI ​​model, of the engine underneath processing your prompts and looking for a response. And being an engine, it is an element that you can use both in Gemini apps and in other applications, as long as they can connect with Gemini to use it.

And this is where Gemini having an API or application programming interface comes into play. APIs are a kind of communication bridge between an app and an external servicein this case the API is used to connect other applications with Gemini.

To give an example, imagine that I want to create an artificial intelligence bot. Within this bot I would need an AI model, an engine that processed my requests. But of course, an artificial intelligence model can weigh gigas or terabytes, and I can’t afford to include it within the app. Then I will have to connect the bot with an external AI hosted on its own servers.

The idea would be that when you write something to my bot, this bot sends my message to the AI, and that when the AI ​​generates the response it reaches the bot and it can show it to me. And since the bot and the AI ​​are on different servers, possibly in different countries, I’m going to need a bridge. And this bridge is the API.

The Gemini API that you can create for free is a key, and it’s like the key to the bridge to connect any service to Gemini. In this way, with the API you will be able to include Gemini in your projects, or link it to third-party pages where you are creating an application or a workflow.

API keys can be paid, but Google also allows you to have a free one for Gemini. The free API has certain limitations in the speed and number of requests, with numbers like 5 requests per minute or 100 per day for Gemini 2.5 Pro. And so, each model has its limits.

But in exchange, what you have is the possibility of use Gemini in your projects to create your own chatbot or assistant, to automate tasks, to analyze texts, videos or audio and make transcriptions and summary, generate code, and ultimately for whatever you need. You will have the AI ​​within the application, but not natively, but you will have connected both.

How to get the free Gemini API

To get the Gemini APIyou will have to go to the Google API management website. For that, go to the website aistudio.google.com and sign in with your Google account. When you do, in the bar on the left at the bottom click on Get API Key.

Now you have to click on the option Create API key that appears at the top of the screen you have created. This will open a window where you have to create the project for which you are going to use it to be able to identify it. When you create the project, you can now create the API.

When you have created the API, you will see that it appears in the list of API keys. You just have to click on the left, below where it says Clueand a window with the API will open, starting with “AIza–“. Now you have the API, and you can link it to third-party services to access Gemini.
