Video

Luo videoleikkeitä asynkronisella tehtävämallilla — lähetä kehote, tee tilakysely ja nouda tulos.

Videon luonti toimii taustalla – suoratoistoa ei ole. Menettely on aina: luo tehtävä → kyselyn tila → lataa MP4. Tehtävät vanhenevat 24 tunnin kuluttua.

1. Luo tehtävä

Lähettää työn ja palauttaa tehtävätunnuksen. Hinta veloitetaan etukäteen perustuen valitun mallin kestoon × sekuntihintaan.

ParameterTypeRequiredDescription
modelstringRequiredVideo model ID. Use /v1/models and filter by output_modalities.includes("video").
promptstringRequiredScene description.
modestringOptional"text" (default), "image" (animate a first-frame image), "reference" (style transfer from one or more frames).
duration_secondsintegerOptionalClip length. Range depends on the model — typically 5, 8 or 10 s. Defaults to the model's minimum.
aspect_ratiostringOptional"16:9", "9:16", "1:1", "4:3" — must be in the model's supported list.
qualitystringOptional"480p", "720p", "1080p" — must be in the model's supported list.
input_imagesarrayOptional[{ url? } | { b64_json? }] — required for "image" and "reference" modes.
seedintegerOptionalReproducibility seed where supported.
soundbooleanOptionalEnable native audio track on models that produce sound (e.g. wan).

Vastaus

ParameterTypeRequiredDescription
task_idstringOptionalPersistent task identifier. Use it on every follow-up endpoint.
statusstringOptional"queued" right after creation.
modelstringOptionalEcho of requested model.
createdintegerOptionalUnix timestamp.
expires_atintegerOptionalUnix timestamp after which the result is purged (typically created + 86400).
cost_centsnumberOptionalUp-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. Tilauskysely

Äänestys 5–15 sekunnin välein. Tehtävät valmistuvat yleensä 30 s – 4 min kestosta ja mallista riippuen. Sama päätepiste palauttaa tuloksen URL-osoitteen, kun tila vaihtuu "valmis".

GEThttps://api.airforce/v1/video/tasks/:task_id
ParameterTypeRequiredDescription
statusstringOptional"queued" | "running" | "completed" | "failed" | "expired".
progressintegerOptional0–100 while running. Absent for queued tasks.
result_urlstringOptionalMP4 download URL once status is "completed". Pre-signed; valid until expires_at.
thumbnail_urlstringOptionalOptional poster frame.
errorobjectOptionalSet when status is "failed". { type, message }.
cost_centsnumberOptionalFinal 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. Suoratoiston edistyminen (valinnainen)

Ohita kyselysilmukka palvelimen lähettämät tapahtumat -streamilla. Lähettää yhden tapahtuman edistymismuutosta kohti ja sulkeutuu, kun tehtävä on päätetilassa. Sama hyötykuorman muoto kuin GET-päätepisteessä.

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. Listaa ja poista

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

Palauttaa viimeaikaiset tehtäväsi (uusimmat ensin). Hyödyllinen kojelaudalle historianäkymän luomiseen.

ParameterTypeRequiredDescription
limitintegerOptionalMax items returned. Default 50, max 200. Pass as a query string.
statusstringOptionalFilter 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

Poistaa tehtävän historiastasi. MP4 poistetaan myös CDN-tallennustilasta. Ei hyvitystä – hinta on jo veloitettu.


Kustannukset ja rajoitukset

Jokainen videomalli paljastaa ominaisuuksien metatiedot, joista voit lukea /v1/models:

ParameterTypeRequiredDescription
video_caps.aspect_ratiosarrayOptionalAllowed aspect_ratio values.
video_caps.qualitiesarrayOptionalAllowed quality values.
video_caps.min_duration_s / max_duration_sintegerOptionalAllowed range for duration_seconds.
video_caps.modesarrayOptionalSubset of ["text", "image", "reference"] supported.
video_caps.price_per_second_centsintegerOptionalCost = 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.
