Se lo stato della risposta è "queued" o "running", interroga GET https://api.doitong.com/v1/requests/REQUEST_ID?wait=20 finché non diventa "succeeded"; i file si trovano in outputs[].url. POST https://api.doitong.com/v1/quote/veo3.1/fast/image-to-video con lo stesso body restituisce il prezzo esatto prima dell'esecuzione.
