How do I determine my GPT API endpoint?

Below is how you can determine and use your GPT API endpoint:

1. Check the API Documentation
   The official OpenAI API documentation details the available endpoints. The base URL is usually:

   https://api.openai.com/v1
   

2. Identify the Specific Endpoint
   Depending on what action you need, you append the relevant path to the base URL. For example:

   • For completions:

     https://api.openai.com/v1/completions
     

   • For chat completions:

     https://api.openai.com/v1/chat/completions
     

3. Example in Python
   Here’s a concise example to illustrate using the completions endpoint in a Python script:

   PYTHONCopied
   import requests
   
   # Replace with your actual API key
   api_key = "YOUR_API_KEY"
   
   # Define the endpoint URL (completions endpoint in this example)
   endpoint = "https://api.openai.com/v1/completions"
   
   headers = {
       "Content-Type": "application/json",
       "Authorization": f"Bearer {api_key}"
   }
   
   data = {
       "model": "gpt-4",       # Adjust model as needed
       "prompt": "Hello, world!",
       "max_tokens": 50
   }
   
   response = requests.post(endpoint, headers=headers, json=data)
   print(response.json())

Use the appropriate endpoint from the documentation based on your operational needs. If you’re ever unsure which endpoint to use, consult the specific section in the API reference for details on the endpoint paths for different actions.
