Introduction

The Lettria Platform at app.lettria.com is used for setting up your project, importing your dataset, collaborating in a group, annotating your data, organising your knowledge, and building your NLP solution.

The Lettria API, on the other hand, is what you will use to build your application with the solution you’ve built on the platform using your data and knowledge.

Using the API, you can easily understand text data that is given as input to the API, using artificial intelligence and natural language processing.

The Lettria API has three main end points:

1. Comprehension

   You can understand the sentiment, meaning, and context of the text input given, and obtain the output in a JSON format, to use it in a variety of industries and applications.

2. Classification

   You can automatically classify text into predefined categories.

3. Structuration

To build your NLP solution using Lettria, follow these steps:

1. Set up an account on the Lettria platform at app.lettria.com.
2. Build your NLP solution using the Lettria platform.
3. Get your API key from the platform.

Then, you can send the text you want to process to the Lettria API via an HTTP request. The API will return a JSON response with the analyzed data, including key elements such as:

• Watchwords
• Sentiment
• Figures

You can leverage this data in your application to gain insights, streamline text processing tasks, or build automated systems for tasks such as customer service, social media monitoring, content moderation, and text classification.
