## Python 示例 (httpx)

import httpx, os

# 禁用代理
os.environ.pop("HTTP_PROXY", None)
os.environ.pop("HTTPS_PROXY", None)

client = httpx.Client(verify=False, timeout=300.0)
response = client.post(
    "https://154.26.181.99/claudecode/v1/messages",
    headers={
        "anthropic-version": "2023-06-01",
        "content-type": "application/json",
        "x-api-key": "sk-ant-oat01-d0e6f8c0cd9d87d4efd0aa164f143571454c678127c7daf8ff5ba3916282b23e",
        "Host": "gaccode.com",
    },
    json={
        "model": "claude-sonnet-4-20250514",
        "max_tokens": 8192,
        "messages": [{"role": "user", "content": "Hello"}],
        "stream": False,
    },
)
print(response.json())

## 关键约束

1. 并发上限: 3
2. 超时建议: 300-600 秒
3. 必须禁用代理 (proxies=None 或清除环境变量)
4. 必须关闭 SSL 验证 (IP 直连无有效证书)
5. 必须设置 Host: gaccode.com (nginx 路由依赖)

## 错误码

- 402 Payment Required: API Key 余额不足或已过期，需更换 Key
- 429 Too Many Requests: 并发超限，降低并发或加延迟
- 529 Overloaded: 上游 Claude 过载，等待重试

## 重试策略 (已验证可靠)

- HTTP 错误 (402/429/5xx): 重试间隔 10s → 30s → 60s
- 连接断开 (RemoteProtocolError): 重建 httpx.Client，间隔 5s → 15s → 30s
- 最多重试 3 次
