Here is my python code, and encountered run time error,

Error: 401 { "statusCode": 401, "message": "Unauthorized. Access token is missing,

invalid, audience is incorrect (), or have expired." }

import requests

# Azure OpenAI Configuration
API_KEY = "xxxxxx"  # API key from Azure OpenAI
ENDPOINT = ";

# API data
payload = {
    "messages": [
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Tell me a joke."}
    ],
    "temperature": 0.7,
    "max_tokens": 100
}

headers = {
    "Content-Type": "application/json",
    "Authorization": f"Bearer {API_KEY}"
}

# API call
response = requests.post(ENDPOINT, headers=headers, json=payload)

if response.status_code == 200:
    print("Response:", response.json())
else:
    print("Error:", response.status_code, response.text)

Apikey&ENDPOINT

I rechecked key and other values and topics related this issue. I can't find anything to solve it.

There will be no problem copying and pasting the key values ​​and other necessary values. API version seem correct.

or, I am using free trial, so need to upgrade subscription? I don't think so.

You use bearer token authorization when you are acquiring the token using Azure AD. Since you are using the API key, you need not do this.

Please change the following code:

headers = {
    "Content-Type": "application/json",
    "Authorization": f"Bearer {API_KEY}"
}

to

headers = {
    "Content-Type": "application/json",
    "api-key": f"{API_KEY}"
}

And you should not get this error.

I fixed it creating another deployment. Thanks!
