  -H "Content-Type: application/json" \

# Doubao Seedance: 5 seconds at 480p
curl -X POST https://api.apimodels.app/v1/video/generations \
  -H "Authorization: Bearer $APIMODELS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "model": "seedance-2.0-mini", "prompt": "steam rising from the mug as sunlight moves across the desk", "resolution": "480p", "duration": 5 }'

# Poll either one: GET /v1/images/generations?task_id=... or /v1/video/generations?task_id=...

Python

import os, time, requests

B = "https://api.apimodels.app/v1"
H = {"Authorization": f"Bearer {os.environ['APIMODELS_API_KEY']}"}

r = requests.post(f"{B}/images/generations", headers=H, json={
    "model": "doubao-seedream-5-0-pro",
    "prompt": "a ceramic coffee mug on a walnut desk, morning light",
    "resolution": "1K", "aspect_ratio": "16:9",
})
task_id = r.json()["data"]["taskId"]

while True:
    d = requests.get(f"{B}/images/generations", headers=H, params={"task_id": task_id}).json()["data"]
    if d["state"] in ("completed", "failed"):
        print(d.get("resultUrls") or d.get("failMsg")); break
    time.sleep(3)

豆包 API key 要钱吗?

在火山方舟和 apimodels.app 上,创建 Key 都不要钱,按调用付费。火山方舟的 Seedance 视频模型另外要求可用余额满 ¥200(或买了符合条件的节省计划、资源包)才能开通。

用豆包 API 需要实名认证吗?

在火山引擎需要:账号完成实名认证后才能购买任何产品或服务。在 apimodels.app 用邮箱注册就能调用 Seedream 和 Seedance,不需要火山引擎账号。

豆包生图用的是哪个模型?

Seedream 系列。最新的是 Seedream 5.5(模型名 doubao-seedream-5-5),Seedream 5.0 Pro、5.0 Flash、5.0 Lite 和 4.5 也都能通过 API 调用。

通过 API 调 Seedream 出的图带水印吗?

在 apimodels.app 上不带:Seedream 5.5、5.0 Pro、5.0 Lite 出的图都没有水印。豆包 App 里的水印设置和 API 是两回事。

能在 apimodels.app 上调豆包的对话模型吗?

不能。这里只有豆包的生图(Seedream)和视频(Seedance)模型。对话模型请到火山方舟调用,base_url 填 https://ark.cn-beijing.volces.com/api/v3。
