提交、轮询、下载

import json
import time
import urllib.request

BASE_URL = "https://api.llmapi.site"
API_KEY = "YOUR_TASK_API_KEY"


def request_json(method, path, payload=None, extra_headers=None):
    data = None
    headers = {
        "Authorization": f"Bearer {API_KEY}",
        "Accept": "application/json",
    }
    if payload is not None:
        data = json.dumps(payload).encode("utf-8")
        headers["Content-Type"] = "application/json"
    if extra_headers:
        headers.update(extra_headers)
    req = urllib.request.Request(BASE_URL + path, data=data, headers=headers, method=method)
    with urllib.request.urlopen(req, timeout=60) as resp:
        return json.loads(resp.read().decode("utf-8"))


task = request_json("POST", "/v1/tasks", {
    "model": "gpt-image-2",
    "modality": "image",
    "params": {
        "model": "gpt-image-2",
        "prompt": "a clean studio product photo of a matte black water bottle",
        "n": 1,
        "image_size": "2K",
        "aspect_ratio": "1:1",
    },
    "metadata": {"source": "python-example"},
}, {"Idempotency-Key": "python-image-order-001"})

task_id = task["id"]

while True:
    detail = request_json("GET", f"/v1/tasks/{task_id}")
    if detail["status"] in {"succeeded", "failed", "timeout", "canceled"}:
        break
    time.sleep(3)

if detail["status"] != "succeeded":
    raise RuntimeError(detail.get("error") or detail["status"])

asset_url = detail["assets"][0]["url"]
with urllib.request.urlopen(asset_url, timeout=60) as resp:
    image_bytes = resp.read()

with open("result.png", "wb") as f:
    f.write(image_bytes)

最小视频提交

先使用 GET /v1/tasks/models 确认当前 Key 已开放目标模型。视频同样使用上面的轮询流程：

video_task = request_json("POST", "/v1/tasks", {
    "model": "seedance-2-0-fast",
    "modality": "video",
    "params": {
        "prompt": "A paper airplane glides across a quiet studio, static camera",
        "duration": 5,
        "resolution": "720p",
        "aspect_ratio": "16:9",
        "generate_audio": False,
    },
    "metadata": {"source": "python-video-example"},
}, {"Idempotency-Key": "python-video-order-001"})

video_task_id = video_task["id"]

参考图 Data URL

import base64


def data_url(path, content_type="image/png"):
    with open(path, "rb") as f:
        encoded = base64.b64encode(f.read()).decode("ascii")
    return f"data:{content_type};base64,{encoded}"

OpenAI 风格重绘请求体

payload = {
    "model": "gpt-image-2",
    "modality": "image",
    "params": {
        "model": "gpt-image-2",
        "prompt": "Replace the background with a premium studio scene.",
        "images": [{"image_url": data_url("input.png")}],
        "n": 1,
        "image_size": "2K",
        "aspect_ratio": "1:1",
        "extra_body": {
            "input_fidelity": "high",
        },
    },
}

Gemini 扩展参数

payload = {
    "model": "gemini-3.1-flash-image",
    "modality": "image",
    "params": {
        "model": "gemini-3.1-flash-image",
        "prompt": "Create a product image using this object.",
        "images": [{"image_url": data_url("input.png")}],
        "n": 1,
        "image_size": "2K",
        "aspect_ratio": "16:9",
        "extra_body": {
            "generationConfig": {
                "temperature": 0.7,
            },
        },
    },
}
