管理金鑰

快速入門

  1. 1

    建立金鑰

    在您的控制台中生成一組 API 金鑰。該金鑰僅顯示一次,請妥善保管。

  2. 2

    呼叫 API

    使用您的 Bearer 金鑰與 Idempotency-Key 標頭發送 POST 請求。

    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"
      }'

    結果投票

    輪詢任務狀態端點,直到狀態為完成或失敗,然後讀取輸出結果。

    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

身份驗證

每個請求皆透過 Authorization 標頭中的 Bearer API 金鑰進行認證。

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.

檢查任務狀態

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_"
    }
  ]
}

錯誤代碼

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)"
  }
}
代碼HTTP含義
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.

搭配 Claude Code 使用

使用 Copy for AI 將完整 API 匯出為乾淨的 Markdown,貼到 Claude Code 或 Codex,讓代理程式自動完成整合串接。或直接將代理程式指向純文字端點。

Skill

在 Claude Code、Codex 或任何代理程式中安裝 Seedance 技能 — 它會自動撰寫電影級提示詞,並透過 API 為你生成影片。

常見問題

誰可以使用 API?
只要有額度的使用者即可使用。沒有方案限制——任何擁有額度的帳戶都能建立金鑰並呼叫API。
如何獲得點數?
前往定價頁面加值或訂閱,點數將即時存入您的帳戶餘額。
網站與 API 的點數是否共用?
是的,您的個人點數額度同時用於網頁生成和 API 呼叫。在團隊中,API 呼叫使用每位成員的個人額度,而非共享的團隊額度。
如何開始?
在儀表板中建立 API 金鑰,然後使用 Bearer token 呼叫端點(請參閱上方快速入門)。
如果呼叫回傳 insufficient_credits,該如何處理?
您的餘額為零,請前往價格頁面充值後重試。
