Chiama il modello H3 Max Extend Video (minimax/h3-max/extend-video) tramite Doitong API. Documentazione per gli agenti: https://doitong.com/it/developers/models/minimax/h3-max/extend-video.md
POST https://vit.doitong.com/api/v1/run/minimax/h3-max/extend-video?wait=20

{
"video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
"prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
Se lo stato della risposta è "queued" o "running", interroga GET https://vit.doitong.com/api/v1/requests/REQUEST_ID?wait=20 finché non diventa "succeeded"; i file si trovano in outputs[].url. POST https://vit.doitong.com/api/v1/quote/minimax/h3-max/extend-video con lo stesso body restituisce il prezzo esatto prima dell'esecuzione.
