openai.Audio.transcribe's `api_key` does not work; openai.error.AuthenticationError is raised

[ftnext]

Describe the bug

When passing the API Key to the api_key parameter of the openai.Audio.transcribe() method, an openai.error.AuthenticationError is thrown.

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "/.../venv/lib/python3.10/site-packages/openai/api_resources/audio.py", line 55, in transcribe
    requestor, files, data = cls._prepare_request(file, file.name, model, **params)
  File "/.../venv/lib/python3.10/site-packages/openai/api_resources/audio.py", line 28, in _prepare_request
    requestor = api_requestor.APIRequestor(
  File "/.../venv/lib/python3.10/site-packages/openai/api_requestor.py", line 130, in __init__
    self.api_key = key or util.default_api_key()
  File "/.../venv/lib/python3.10/site-packages/openai/util.py", line 186, in default_api_key
    raise openai.error.AuthenticationError(
openai.error.AuthenticationError: No API key provided. You can set your API key in code using 'openai.api_key = <API-KEY>', or you can set the environment variable OPENAI_API_KEY=<API-KEY>). If your API key is stored in a file, you can point the openai module at it with 'openai.api_key_path = <PATH>'. You can generate API keys in the OpenAI web interface. See https://onboard.openai.com for details, or email [email protected] if you have any questions.

Upon inspecting the trace back, it seems that the cause is that the api_key is not passed to the _prepare_request method.

When making the following modification, the AuthenticationError is not thrown and the transcription result is obtained.

-        requestor, files, data = cls._prepare_request(file, file.name, model, **params)
+        requestor, files, data = cls._prepare_request(file, file.name, model, api_key=api_key, **params)

To Reproduce

1. pip install openai
2. Create sample.wav (example: say 親譲りの無鉄砲で子供の時から損ばかりしている -o sample.wav --data-format=LEF32@16000)
3. Run the following snippets

Code snippets

>>> OPENAI_API_KEY = "sk-***"
>>> import openai
>>> with open("sample.wav", "rb") as audio_file:
...   transcript = openai.Audio.transcribe("whisper-1", audio_file, api_key=OPENAI_API_KEY)
