What Is The ChatGPT API?

The ChatGPT API, provided by OpenAI, lets developers (and curious beginners) send prompts to the ChatGPT language model and receive smart, human-like responses. You can use it for chatbots, content generation, virtual assistants, and more.

What You Need To Get Started

An OpenAI account (sign up at platform.openai.com).

Step-By-Step: How To Use ChatGPT API

Sign up at OpenAI: Go to the OpenAI platform and create an account.
Get your API key: Inside your account dashboard, generate an API key. Keep it secret!
Install API tools: Use tools like Postman to test, or set up a development environment (Python, Node.js, etc.).
Send your first API request: Use a POST request to the endpoint https://api.openai.com/v1/chat/completions with your prompt and model (like gpt-3.5-turbo).
Handle the response: Display or use the generated text in your app or system.
