Python openai.Model.list() Fails with 'Resource not found' Error Despite Valid API Key

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I can successfully list models using curl and Postman (with the custom header "Host" enabled), but my Python script fails with the error below.

I confirmed my environment is set up correctly:

BASH
(base) sergio@Ubuntu-22-04-Python:~/Testingdalle$ python --version  
Python 3.10.11  

(base) sergio@Ubuntu-22-04-Python:~/Testingdalle$ openai --version  
openai 0.27.8

My Python Script

PYTHON
import openai  

openai.api_key = “mykeyhere”  
openai.organization = “myorghere”  
openai.Model.list()

Error Thrown

BASH
(base) sergio@Ubuntu-22-04-Python:~/Testingdalle$ ./create_painting.py  
Traceback (most recent call last):  
  File “/home/sergio/Testingdalle/./create_painting.py”, line 16, in

    response, _, api_key = requestor.request(  
  File “/home/sergio/.local/lib/python3.10/site-packages/openai/api_requestor.py”, line 298, in request  
    resp, got_stream = self._interpret_response(result, stream)  
  File “/home/sergio/.local/lib/python3.10/site-packages/openai/api_requestor.py”, line 700, in _interpret_response

    raise self.handle_error_response(  
openai.error.InvalidRequestError: Resource not found

I also tried encoding the API key using openai.api_key.encode('utf-8'), but that didn’t resolve the issue.

Since I can create API keys and the endpoint works with curl/Postman, my API account appears to be valid. Any help in identifying the discrepancy in the Python environment would be appreciated.

Below is one likely explanation and fix. In your curl/Postman tests you’re adding a custom “Host” header so that your request is routed to the correct endpoint. In contrast, the python openai library uses a fixed endpoint (https://api.openai.com by default) and automatically builds its headers. If you’re using a custom endpoint (or a cloud provider like Azure OpenAI) that requires a specific Host header, you must configure the client accordingly.

Steps to Fix

Set the API Base URL

If you’re connecting to a non-standard endpoint (for example, an Azure OpenAI instance or a reverse proxy), set the API base URL. For example:

PYTHON
import openai

openai.api_key = "mykeyhere"
openai.organization = "myorghere"

# For a custom endpoint, e.g., Azure OpenAI
# Replace with your endpoint URL
openai.api_base = "https://<YOUR_CUSTOM_ENDPOINT>"
# If using Azure OpenAI, also specify the type and version:
# openai.api_type = "azure"
# openai.api_version = "2023-03-15-preview"

models = openai.Model.list()
print(models)

By setting the openai.api_base, you instruct the library to use your custom endpoint which likely takes care of the required Host header automatically.

Double-check Your Credentials

Ensure that the API key and organization strings (or Azure keys if applicable) are correct; a misconfiguration can also result in errors like “Resource not found.”
Verify Endpoint Compatibility

If you’re on a platform like Azure OpenAI, note that the endpoints and supported operations (like model listing) can differ. You may need to check the provider’s documentation for any additional required settings.

Summary

The error occurs because the Python library is contacting an endpoint that does not match the one you’re using with curl/Postman (which had a custom Host header). Configuring the client to use the correct endpoint via openai.api_base (and setting additional parameters if needed) should resolve the issue.

Give that a try and your Python script should be able to list the models just as curl/Postman does.
