Sleutel aanmaken
Genereer een API-sleutel in je dashboard. Deze wordt slechts één keer getoond, dus bewaar hem op een veilige plek.

API aanroepen
Stuur een POST-verzoek met je Bearer key en een Idempotency-Key-header.
curl -X POST https://www.seedance2ai.io/api/v1/video/seedance2 \ -H "Authorization: Bearer $SEEDANCE_API_KEY" \ -H "Content-Type: application/json" \ -H "Idempotency-Key: demo-video-001" \ -d '{ "mode": "text-to-video", "quality_tier": "standard", "prompt": "A cinematic shot of a glass train crossing a snowy mountain bridge", "aspect_ratio": "16:9", "duration": "5", "resolution": "720p" }' - 3
Resultaat opvragen
Bevraag het taakstatus-eindpunt totdat de status 'voltooid' of 'mislukt' is, en lees dan de uitvoer.
while true; do TASK=$(curl -s https://www.seedance2ai.io/api/v1/tasks/sd2_xxxxx \ -H "Authorization: Bearer $SEEDANCE_API_KEY") STATUS=$(echo "$TASK" | jq -r '.status') if [ "$STATUS" = "completed" ] || [ "$STATUS" = "failed" ]; then echo "$TASK" | jq break fi sleep 10 done
Authenticatie
Elk verzoek wordt geauthenticeerd met een Bearer API-sleutel in de Authorization-header.
- Base URL
https://www.seedance2ai.io/api/v1- Idempotency-Key
- Send a unique value with every POST. Retrying with the same key and body within 24 hours returns the original task instead of charging for a second one.
- Credits
- Calls spend credits from the key owner's personal balance. Team credits are not used.
- Media URLs
- Reference images, videos and audio must be public HTTPS URLs that can be fetched without cookies or a login.

Seedance prompt guide
Seedance prompts work best as concrete director instructions. Describe the subject, action, scene, camera motion, visual style, and constraints, then map every reference asset to the right API parameter.
- Use image_url for the opening frame, end_image_url for the closing frame, and media_urls for character, motion, style, source-video, or extension references.
- Describe asset roles in natural language inside prompt. Do not send raw asset ids, asset:// URLs, or in-app-only labels such as @图片1.
- For edits say “strictly edit the supplied source video”; for extensions say “continue from the supplied previous clip.”
- For complex scenes, use ordered shots plus a style and constraint package: stable faces, natural motion, no deformation, no watermark, no logo, and no subtitles unless intended.

Taakstatus controleren
/api/v1/tasks/{id}status
processing- Accepted and running. Keep polling.
completed- Finished. Read output, or result_urls for a flat list of files.
failed- Ended without a result. error says why and credits_refunded shows what was returned.
Poll every 10 seconds or so and stop at completed or failed. Status reads have their own rate limit, so polling never uses up your submit budget.

doneTasks and balance
Read endpoints for building a task history, showing remaining credits, or discovering models at runtime. They share the read rate limit.
List tasks
/api/v1/tasksReturns the tasks this account created through the API in the last 30 days, newest first. Each item has the same shape as a single task. Use limit (1 to 50, default 20) and pass next_cursor as before to fetch the next page.
curl "https://www.seedance2ai.io/api/v1/tasks?limit=20" \
-H "Authorization: Bearer $SEEDANCE_API_KEY"{
"data": [
{
"id": "sd2_xxxxx",
"type": "video",
"status": "completed",
"model": "seedance2",
"credits_used": 30,
"result_urls": ["https://..."]
}
],
"has_more": false,
"next_cursor": null
}Check balance
/api/v1/balanceReturns the credits the key owner can spend through the API. subscription_credits is the part that came from a plan and expires at subscription_credits_expire_at.
curl "https://www.seedance2ai.io/api/v1/balance" \
-H "Authorization: Bearer $SEEDANCE_API_KEY"{
"credits": 1200,
"subscription_credits": 1000,
"subscription_credits_expire_at": "2026-07-01T00:00:00.000Z"
}List models
/api/v1/modelsReturns every model the API serves with its endpoint, accepted modes and task ID prefix. Useful for building a model picker without hard-coding this page.
curl "https://www.seedance2ai.io/api/v1/models" \
-H "Authorization: Bearer $SEEDANCE_API_KEY"{
"data": [
{
"id": "seedance2",
"name": "Seedance 2.0",
"type": "video",
"method": "POST",
"endpoint": "/api/v1/video/seedance2",
"modes": ["text-to-video", "image-to-video", "media-to-video"],
"task_id_prefix": "sd2_"
}
]
}Foutcodes
Every error has the same shape. Branch on code, and show message to a person. A task that was accepted can still fail later, so also check status when you poll.
{
"error": {
"code": "invalid_request",
"message": "Invalid request body: prompt: String must contain at least 3 character(s)"
}
}| Code | HTTP | Betekenis |
|---|---|---|
unauthorized | 401 | Missing, invalid, or revoked API key. |
invalid_request | 400 | Bad input or unsupported field. The message names the first field that failed; details lists them all. |
purchase_required | 403 | Seedance 2.5 requires a successful credits or plan purchase; free promotional credits alone do not unlock it. The GPT Image 2.5 economy channel has the same requirement. |
insufficient_credits | 402 | Not enough credits. Seedance 2.5 always returns HTTP 402 with insufficient_credits; when an authoritative quote is available, it may also include required_credits, available_credits, pricing_version, and promotion_applied. |
rate_limited | 429 | Too many requests for this account. See Rate limits below. Seedance requests that validate reference media are limited to 3 per 60 seconds per account and source IP, with a project-wide safety cap. Retry after the Retry-After response header (in seconds). |
idempotency_conflict | 409 | Same Idempotency-Key reused with a different body, or still running. |
service_busy | 503 | Temporary upstream or credit-concurrency issue. Retry. |
not_found | 404 | Task does not exist or does not belong to this key owner. |
internal_error | 500 | Unexpected server-side failure. |
Rate limits
A request over the limit returns HTTP 429 with a Retry-After header in seconds, plus X-RateLimit-Limit and X-RateLimit-Reset. Wait that long, then retry with the same Idempotency-Key.

- Wie kan de API gebruiken?
- Iedereen met credits. Er is geen planbeperking — elk account met credits kan een sleutel aanmaken en de API aanroepen.
- Hoe krijg ik credits?
- Waardeer op of abonneer je op de prijzenpagina. Credits worden direct aan je saldo toegevoegd.
- Worden credits gedeeld tussen de website en de API?
- Ja — je persoonlijke creditsaldo wordt gebruikt voor zowel webgeneratie als API-aanroepen. In een team gebruiken API-aanroepen het eigen persoonlijke creditsaldo van elk lid, niet de gedeelde teampool.
- Hoe begin ik?
- Maak een API-sleutel aan in je dashboard en roep de endpoints aan met een Bearer-token (zie Quickstart hierboven).
- Wat als een call insufficient_credits retourneert?
- Je saldo is leeg — laad op via de prijzenpagina en probeer het opnieuw.
