快速开始
下面用一个最小解说视频请求演示完整流程。正式环境基础地址为：
https://api.kpainter.ai/openapi/v11. 准备 API Key
在 API Key 页面 激活并复制你的 Key，然后保存到服务端环境变量。不要把 Key 放进网页前端或日志。
export KPAINTER_API_KEY="<your_api_key>"export KPAINTER_BASE_URL="https://api.kpainter.ai/openapi/v1"import requests BASE_URL = "https://api.kpainter.ai/openapi/v1"HEADERS = { "Authorization": "Bearer <your_api_key>",}2. 校验账号
curl -s "$KPAINTER_BASE_URL/me" \ -H "Authorization: Bearer $KPAINTER_API_KEY"me = requests.get(f"{BASE_URL}/me", headers=HEADERS, timeout=30)me.raise_for_status()print(me.json())3. 读取当前能力
curl -s "$KPAINTER_BASE_URL/capabilities" \ -H "Authorization: Bearer $KPAINTER_API_KEY"capabilities = requests.get( f"{BASE_URL}/capabilities", headers=HEADERS, timeout=30,).json()print(capabilities["products"])从返回结果选择视频时长、音色、模板和表达风格。不要把页面示例里的值当成永久配置。
4. 创建内容
curl -s "$KPAINTER_BASE_URL/creations" \ -H "Authorization: Bearer $KPAINTER_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "type": "video", "prompt": "面向新员工解释一次客户问题升级流程", "instructions": "使用简洁、专业的表达，保留原有术语", "max_credits": 300, "video": { "duration_seconds": 120, "aspect_ratio": "16:9", "language": "zh" } }'payload = { "type": "video", "prompt": "面向新员工解释一次客户问题升级流程", "instructions": "使用简洁、专业的表达，保留原有术语", "max_credits": 300, "video": { "duration_seconds": 120, "aspect_ratio": "16:9", "language": "zh", },}creation = requests.post( f"{BASE_URL}/creations", headers=HEADERS, json=payload, timeout=30,)creation.raise_for_status()creation_id = creation.json()["id"]5. 查询进度
创建和编辑都是异步任务。保存返回的 creation id，并持续查询同一个结果即可。
import time while True: response = requests.get( f"{BASE_URL}/creations/{creation_id}", headers=HEADERS, timeout=30, ) response.raise_for_status() creation = response.json() print( creation["status"], creation["progress_pct"], creation.get("estimated_remaining_seconds"), creation.get("estimated_credits"), ) if creation["status"] in {"ready", "failed", "paused"}: break time.sleep(5)6. 获取结果
只有 ready 或 has_usable_delivery 为 true 时才读取输出：
outputs = requests.get( f"{BASE_URL}/creations/{creation_id}/outputs", headers=HEADERS, timeout=30,)outputs.raise_for_status()print(outputs.json()["outputs"])返回的 URL 才是可交付结果。不要自行拼接存储路径。
带附件时
先调用 POST /files 上传文件，取得 file_id，再把它放入 input_file_ids。三种产品都支持附件。完整示例见 创建与查询。
