API REFERENCE

Video

Genera clip video con un modello di attività asincrono: invia un prompt, esegui un sondaggio sullo stato e recupera il risultato.

La generazione del video viene eseguita in background: non è disponibile alcun rendering in streaming. Il flusso è sempre: crea attività → stato sondaggio → scarica MP4. Le attività scadono dopo 24 ore.

1. Crea un'attività

Invia il lavoro e restituisce un ID attività. Il costo viene addebitato in anticipo in base alla durata × al prezzo al secondo del modello scelto.

Modelli video

…· live

Parameter	Type	Required	Description
model	string	Required	Video model ID. Use /v1/models and filter by output_modalities.includes("video").
prompt	string	Required	Scene description.
mode	string	Optional	"text" (default), "image" (animate a first-frame image), "reference" (style transfer from one or more frames).
duration_seconds	integer	Optional	Clip length. Range depends on the model — typically 5, 8 or 10 s. Defaults to the model's minimum.
aspect_ratio	string	Optional	"16:9", "9:16", "1:1", "4:3" — must be in the model's supported list.
quality	string	Optional	"480p", "720p", "1080p" — must be in the model's supported list.
input_images	array	Optional	[{ url? } \| { b64_json? }] — required for "image" and "reference" modes.
seed	integer	Optional	Reproducibility seed where supported.
sound	boolean	Optional	Enable native audio track on models that produce sound (e.g. wan).

Risposta

Parameter	Type	Required	Description
task_id	string	Optional	Persistent task identifier. Use it on every follow-up endpoint.
status	string	Optional	"queued" right after creation.
model	string	Optional	Echo of requested model.
created	integer	Optional	Unix timestamp.
expires_at	integer	Optional	Unix timestamp after which the result is purged (typically created + 86400).
cost_cents	number	Optional	Up-front cost debited from your balance. Refunded if the task ultimately fails.

{
  "task_id": "vid_01HXY1234ABCD",
  "status": "queued",
  "model": "wan-2.6",
  "created": 1715000000,
  "expires_at": 1715086400,
  "cost_cents": 320
}

2. Sondaggio per lo stato

Sondaggio ogni 5-15 secondi. Le attività vengono solitamente completate in 30 secondi – 4 minuti a seconda della durata e del modello. Lo stesso endpoint restituisce l'URL del risultato quando lo stato passa a "completato".

GEThttps://api.airforce/v1/video/tasks/:task_id

Parameter	Type	Required	Description
status	string	Optional	"queued" \| "running" \| "completed" \| "failed" \| "expired".
progress	integer	Optional	0–100 while running. Absent for queued tasks.
result_url	string	Optional	MP4 download URL once status is "completed". Pre-signed; valid until expires_at.
thumbnail_url	string	Optional	Optional poster frame.
error	object	Optional	Set when status is "failed". { type, message }.
cost_cents	number	Optional	Final cost. Equals the create-time cost on success.

{
  "task_id": "vid_01HXY1234ABCD",
  "status": "completed",
  "progress": 100,
  "result_url": "https://cdn.api.airforce/video/vid_01HXY1234ABCD.mp4",
  "thumbnail_url": "https://cdn.api.airforce/video/vid_01HXY1234ABCD.jpg",
  "model": "wan-2.6",
  "duration_seconds": 8,
  "expires_at": 1715086400,
  "cost_cents": 320
}

2b. Avanzamento dello streaming (facoltativo)

Salta il ciclo di polling con un flusso di eventi inviati dal server. Emette un evento per ogni modifica di avanzamento e si chiude una volta che l'attività è in uno stato terminale. Stessa forma del carico utile dell'endpoint GET.

GEThttps://api.airforce/v1/video/tasks/:task_id/stream

event: progress
data: {"task_id":"vid_01HXY...","status":"running","progress":12}

event: progress
data: {"task_id":"vid_01HXY...","status":"running","progress":58}

event: completed
data: {"task_id":"vid_01HXY...","status":"completed","progress":100,"result_url":"https://cdn.api.airforce/video/vid_01HXY....mp4"}

3. Elenca ed elimina

GEThttps://api.airforce/v1/video/tasks

Restituisce le attività recenti (prima la più recente). Utile per il dashboard per eseguire il rendering di una visualizzazione della cronologia.

Parameter	Type	Required	Description
limit	integer	Optional	Max items returned. Default 50, max 200. Pass as a query string.
status	string	Optional	Filter to one status, e.g. ?status=running.

curl "https://api.airforce/v1/video/tasks?limit=20&status=completed" \
  -H "Authorization: Bearer sk-air-YOUR_API_KEY"

DELETEhttps://api.airforce/v1/video/tasks/:task_id

Rimuove l'attività dalla cronologia. Anche l'MP4 viene eliminato dall'archivio CDN. Nessun rimborso: il costo era già stato addebitato.

Costi e vincoli

Ogni modello video espone metadati di funzionalità da cui è possibile leggere /v1/models:

Parameter	Type	Required	Description
video_caps.aspect_ratios	array	Optional	Allowed aspect_ratio values.
video_caps.qualities	array	Optional	Allowed quality values.
video_caps.min_duration_s / max_duration_s	integer	Optional	Allowed range for duration_seconds.
video_caps.modes	array	Optional	Subset of ["text", "image", "reference"] supported.
video_caps.price_per_second_cents	integer	Optional	Cost = duration_seconds × this value.

Cost is debited at task creation. Failed tasks (status "failed" or "expired") refund the cost.
Max 4 concurrent video tasks per API key.
Result URLs are pre-signed and stop working at expires_at. Download or copy the MP4 to your own storage if you need it longer.

    ).then(r => r.json());

    if (task.status === 'completed') return task.result_url;
    if (task.status === 'failed' || task.status === 'expired') {
      throw new Error(task.error?.message ?? task.status);
