路徑參數
如果建立請求的響應中包含 poll_url，建議優先調用該 URL 進行輪詢。某些圖片任務可能會在 /v1/tasks/{id} 下顯示 poll_url，而非圖片特定的狀態路徑。If the task no longer exists or can no longer be resolved through the public async-task contract, LemonData returns async_task_not_found with the message Task not found or no longer available.
任務狀態：pending、processing、completed 或 failed。
生成的圖片陣列（當 status 為 completed 時填充）。每個物件包含：
url (string): 生成圖片的 URLrevised_prompt (string): 用於生成的提示詞
錯誤訊息（僅在 status 為 failed 時出現）。
curl "https://api.lemondata.cc/v1/tasks/ldtask_aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" \
-H "Authorization: Bearer sk-your-api-key"
{
"created": 1706000000,
"id": "ldtask_aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",
"task_id": "ldtask_aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",
"poll_url": "/v1/tasks/ldtask_aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",
"status": "pending",
"data": [
{
"url": "",
"revised_prompt": "a beautiful sunset over mountains"
}
]
}
輪詢最佳實踐
建議輪詢間隔：3-5 秒。大多數圖片生成任務會在 30-120 秒內完成，具體取決於模型和路由的供應商路徑。
import requests
import time
def poll_image_task(task_id, api_key, max_wait=300, interval=3):
"""Poll for image generation result with timeout."""
url = f"https://api.lemondata.cc/v1/tasks/{task_id}"
headers = {"Authorization": f"Bearer {api_key}"}
start_time = time.time()
while time.time() - start_time < max_wait:
response = requests.get(url, headers=headers)
data = response.json()
if data["status"] == "completed":
return data["data"][0]["url"]
elif data["status"] == "failed":
raise Exception(data.get("error", "Generation failed"))
time.sleep(interval)
raise TimeoutError(f"Task {task_id} did not complete within {max_wait}s")
# Usage
image_url = poll_image_task("ldtask_aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa", "sk-your-api-key")
print(f"Generated image: {image_url}")
