import requests
import time

def call_dmxapi_image(prompt: str, api_key: str, max_retries=3):
    url = "https://www.dmxapi.cn/v1/images/generations"
    headers = {"Authorization": f"Bearer {api_key}"}
    payload = {"prompt": prompt, "n": 1, "size": "1024x1024"}
    
    retry_delay = 5  # 初始等待秒数
    for attempt in range(max_retries):
        try:
            resp = requests.post(url, headers=headers, json=payload, timeout=10)
            resp.raise_for_status()  # 抛出HTTP错误
            return resp.json()
        except requests.exceptions.HTTPError as e:
            if e.response.status_code == 429:
                print(f"⚠️ 请求过频，第{attempt+1}次重试（等待{retry_delay}s）")
                time.sleep(retry_delay)
                retry_delay *= 2  # 指数退避
            else:
                raise  # 其他错误直接抛出
    raise Exception("❌ 多次重试仍失败，请降低请求频率")

# 使用示例
result = call_dmxapi_image("a cute cat", "YOUR_DMXAPI_KEY")
