原文：API rate limit reached. Please try again later.
译文：API速率限制已达到。请稍后再试。

2. 原因分析

3. 解决方案

python
import time
import requests
def call_api_with_retry(url, headers, data, max_retries=3, initial_delay=5):
    delay = initial_delay
    for attempt in range(max_retries):
        try:
            response = requests.post(url, headers=headers, json=data)
            response.raise_for_status()  # 抛出HTTP错误（含429）
            return response.json()
        except requests.exceptions.HTTPError as e:
            if e.response.status_code == 429:
                print(f"速率限制触发，第{attempt+1}次重试（等待{delay}s）...")
                time.sleep(delay)
                delay *= 2  # 指数退避（5→10→20s）
            else:
                raise  # 非速率错误直接抛出
    raise Exception("超过最大重试次数，API调用失败")
使用示例

try:
    result = call_api_with_retry(
        url="https://api.dmxapi.com/your-endpoint",
        headers={"Authorization": "Bearer YOUR_TOKEN"},
        data={"key": "value"}
    )
except Exception as e:
    print(f"最终失败: {e}")

4. 预防措施

以上方案可直接适配你的嵌入式代理场景，重点是通过重试+退避平滑超出限制的请求。
