Hello, OpenRouter Support Team,

I am trying to use the openai/tts-1-hd audio model via my API key, but I am consistently receiving a "405 Method Not Allowed" error.

I have already confirmed the following points:

My API key works perfectly for text models (like Claude 3).

My account has available credits (currently $4.57).

The error is not with my automation tool (n8n), as the same 405 error occurs when making a direct call via cURL.

I would like to request that you verify if my API key is correctly enabled for using OpenAI's audio models.

My API key starts with: sk-or-v1-96c8...

Thank you.
