OpenAI's own transcription wire
OpenAI's own transcription wire: POST multipart/form-data with a `file` part and get the transcript back. Point any Whisper-shaped SDK at this gateway and pay per call with USDC, no account and no API key. Same model and same four-minute cap as /api/transcribe, which takes a URL instead of an upload; /v1/pro/audio/transcriptions takes it to ten minutes.
