Speech

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

POST /v1/audio/speech

Buy spoken audio at auction, in the OpenAI speech format.

Send model and input. voice is optional when the offers have a default. instructions sets a style line, and input can be an array of turns for more than one speaker. The response body is the audio file. Only a deployment registered to produce speech can win. The price is per character of input, so the cap is exactly the charge.

The body carries audio, so the exchange block is in the x-liquid-exchange header, as JSON. The cap and the job id are in x-liquid-cap-usd and x-liquid-job-id.

There is no streaming form.
