## **What is [Named Entity Recognition](http://www.edenai.co/feature/named-entity-recognition) (NER)?**

Named Entity Recognition (NER) is a subtask of Natural Language Processing (NLP) that aims to identify and classify named entities in text into predefined categories such as person names, organizations, locations, medical codes, time expressions, quantities, monetary values, percentages, etc.

This process helps to extract structured information from unstructured text, making it easy to understand and analyze the content. Named Entity Recognition can be used in various cases, such as sentiment analysis, information retrieval, and text summarization to extract relevant information.

## **Get Started with NER API using JavaScript**

The first step is to set Axios, a promise-based HTTP client for the browser and Node.js, that will allow you to call Eden AI API.

## **How to use NER API with JavaScript**

You are now ready to process text into Eden AI NER API. You can access the list of languages supported in our documentation [here](https://docs.edenai.co/reference/text_named_entity_recognition_create?referral=how-to-ner-javascript).
‍

### **1. Get your NER API Key on Eden AI**

To perform NER, you'll need to create an account on [Eden AI](https://app.edenai.run/user/register?referral=how-to-ner-javascript) for free. Then, you'll be able to get your **API key** directly from the homepage with free credits offered by Eden AI.

### **2. Let’s Detect Named Entities (NER) in Text**

Now that you have imported packages on JavaScript and got your API key, you will be able to detect named entities in your text. With Eden AI, you can choose from a wide range of engines you want for NER. You can access the list of NER providers available on Eden AI directly on our [documentation](https://docs.edenai.co/reference/text_named_entity_recognition_create?referral=how-to-ner-javascript).
‍

For example, we called two different NER engines. Here is the JS code to configure the request:

‍

Then, you'll need to launch the request and print the result:

‍

Here is an example of a NER API response:
