Transcriptions

The OpenAPI 3.1 document is the full description, including schemas:

https://router.inference.ai.exchange/v1/openapi.json

POST /v1/audio/transcriptions

Buy a transcript at auction, in the OpenAI transcription format.

Send multipart/form-data with model and file, or JSON with model and one audio entry in input_references. Only a deployment registered to transcribe can win.

The price is per second of audio. The router reads the length from the bytes of the file, and that length times the offer rate is the estimate and the cap. The charge is the seconds that the provider metered, never above the cap. The exchange block of the response, or the x-liquid-exchange header for the text format, shows the charge.

The router reads WAV, FLAC, MP3, Ogg, WebM, M4A and AAC, whatever the file name. It refuses a file over 25 MB, over two hours, or with no readable length. There is no streaming form, and no srt or vtt format.
