Gebruik dit endpoint om de status te lezen van een taak die is aangemaakt via Een Seedance-video maken. De id in het pad is de waarde die door de create-aanroep wordt teruggegeven, ongeacht welk Seedance-model de taak heeft geproduceerd. De response body is het videotaakobject zelf. Lees status, progress en video_url op het hoogste niveau.

Statusmachine

De API retourneert statusstrings in kleine letters. queued en in_progress zijn niet-terminaal; completed, failed en error zijn terminaal en de taak verandert daarna niet meer.

Status	Betekenis	Terminaal
`queued`	Geaccepteerd en in de wachtrij geplaatst voor rendering.	nee
`in_progress`	Rendering is bezig.	nee
`completed`	Voltooid. `video_url` is aanwezig in de response.	ja
`failed`	De provider heeft de taak afgewezen.	ja
`error`	Een interne fout verhinderde voltooiing.	ja

Pollfrequentie

Poll elke 10 tot 20 seconden. De meeste taken zijn binnen 1 tot 3 minuten klaar, afhankelijk van model, duur en grootte.

Velden om in de gaten te houden

status — bepaalt de stopvoorwaarde voor je pollinglus.
progress — geheel getal van 0 tot 100 dat je in een UI kunt tonen.
video_url — ondertekende download-URL, aanwezig in completed-responses. Seedance-downloads gebruiken deze URL rechtstreeks in plaats van een aparte route /v1/videos/{id}/content. De handtekening is tijdelijk geldig; download of host het bestand opnieuw voordat de handtekening verloopt.
completed_at — optionele Unix-timestamp die door het platform wordt teruggegeven. Gebruik deze niet om polling te stoppen; gebruik in plaats daarvan status.
model — geeft de Seedance-model-id terug die is gebruikt toen de taak werd aangemaakt.

Veelvoorkomende fouten

HTTP 400 met message: "task_not_exist" betekent dat de id onbekend is. Controleer of je de id uit een succesvolle POST /v1/videos-response hebt vastgelegd en dat je die letterlijk gebruikt.
HTTP 401 betekent dat het bearer token ontbreekt of ongeldig is. Controleer of de request-header Authorization: Bearer $COMETAPI_KEY is.

Autorisaties

Authorization

string

header

vereist

Bearer token authentication. Use your CometAPI key.

Padparameters

string

vereist

Task id returned by POST /v1/videos.

Respons

Current Seedance video task state.

string

vereist

Task id.

object

string

vereist

Object type, always video.

model

string

vereist

Model id that generated the task.

status

enum<string>

vereist

Task status. queued and in_progress are non-terminal. completed, failed, and error are terminal.

Beschikbare opties:

queued,

in_progress,

completed,

failed,

error

progress

integer

vereist

Completion percentage.

Vereist bereik: 0 <= x <= 100

created_at

integer

vereist

Task creation time as a Unix timestamp in seconds.

video_url

string | null

Signed download URL for the finished video. Present on completed responses. Seedance downloads use this URL directly instead of a separate /v1/videos/{id}/content route. The signature is time-limited, so download or re-upload the file to your own storage soon after you receive it.

completed_at

integer | null

Optional Unix timestamp returned by the platform. Use status, not this field, to decide when polling can stop.
