Single file transcription only - Upload via Data Stream

Endpoint for single file request for API.This endpoint supports MP3, WAV, and FLAC formats.

Audio files must be provided using the audio_data parameter:

- audio_data: <base64_encoded_audio_string> (the audio file must be encoded in Base64 format before being sent)

This method is useful for direct API requests where sending raw binary files is not possible. Ensure that the encoded string correctly represents the entire audio file to avoid errors.
