Genel API

Kendi araçlarınızdan video ve görseller üretin

Bir anahtar oluşturun, API'yi Bearer auth ile çağırın ve sonucunuz hazır olana kadar görev durumunu yoklayın. Claude Code, Codex ve herhangi bir HTTP istemcisiyle çalışır.

Anahtarları Yönet

Hızlı Başlangıç

  1. 1

    Anahtar Oluştur

    Panonuzda bir API anahtarı oluşturun. Yalnızca bir kez gösterilir, bu yüzden güvenli bir yerde saklayın.

  2. 2

    API'yi çağır

    POST isteğinizi, Bearer anahtarınız ve bir Idempotency-Key başlığı ile gönderin.

    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. 3

    Sonucu sorgula

    Görev durumu tamamlanana veya başarısız olana kadar durum uç noktasını yoklayın, ardından çıktıyı okuyun.

    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

Kimlik Doğrulama

Her istek, Authorization başlığındaki bir Bearer API anahtarı ile doğrulanır.

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.
http
Authorization: Bearer sk_live_your_api_key
Content-Type: application/json
Idempotency-Key: a-unique-id-per-request

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.

Görev Durumunu Kontrol Et

GET
/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.

Tasks 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

GET
/api/v1/tasks

Returns 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"
json
{
  "data": [
    {
      "id": "sd2_xxxxx",
      "type": "video",
      "status": "completed",
      "model": "seedance2",
      "credits_used": 30,
      "result_urls": ["https://..."]
    }
  ],
  "has_more": false,
  "next_cursor": null
}

Check balance

GET
/api/v1/balance

Returns 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"
json
{
  "credits": 1200,
  "subscription_credits": 1000,
  "subscription_credits_expire_at": "2026-07-01T00:00:00.000Z"
}

List models

GET
/api/v1/models

Returns 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"
json
{
  "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_"
    }
  ]
}

Hata kodları

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.

json
{
  "error": {
    "code": "invalid_request",
    "message": "Invalid request body: prompt: String must contain at least 3 character(s)"
  }
}
KodHTTPAnlam
unauthorized401Missing, invalid, or revoked API key.
invalid_request400Bad input or unsupported field. The message names the first field that failed; details lists them all.
purchase_required403Seedance 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_credits402Not 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_limited429Too 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_conflict409Same Idempotency-Key reused with a different body, or still running.
service_busy503Temporary upstream or credit-concurrency issue. Retry.
not_found404Task does not exist or does not belong to this key owner.
internal_error500Unexpected 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.

Submit a job
30 per 60 seconds
Every POST endpoint, counted per account across all of its keys.
Read
120 per 60 seconds
Task status, task list, balance and models. Counted separately, so polling never uses up the submit budget.
Reference media validation
3 per 60 seconds
Seedance requests that include reference media, per account and source IP.

SSS

API'yi kimler kullanabilir?
Kredisi olan herkes. Plan engeli yoktur — kredisi olan her hesap bir anahtar oluşturup API'yi çağırabilir.
Kredileri nasıl alabilirim?
Fiyatlandırma sayfasından bakiye yükleyin veya abone olun. Krediler anında bakiyenize eklenir.
Web sitesi ve API kredileri paylaşılıyor mu?
Evet — kişisel kredi bakiyeniz hem web üretiminiz hem de API çağrılarınız için kullanılır. Bir ekipte, API çağrıları her üyenin kendi kişisel bakiyesini kullanır, ortak ekip havuzunu değil.
Nasıl başlarım?
Kontrol panelinizde bir API anahtarı oluşturun, ardından uç noktaları bir Bearer token ile çağırın (yukarıdaki Hızlı Başlangıç'a bakın).
Bir çağrı insufficient_credits döndürürse ne olur?
Bakiyeniz boş — fiyatlandırma sayfasından yükleyip tekrar deneyin.
