常见报错排查
错误 1：401 Unauthorized - API Key 无效
报错信息：{"error": "Invalid API key or insufficient permissions"}
原因：HolySheep API Key 填写错误或已过期。
解决代码：
# 检查 API Key 是否正确配置
import os
API_KEY = os.environ.get("HOLYSHEEP_API_KEY")
if not API_KEY or len(API_KEY) < 20:
raise ValueError("请检查 HOLYSHEEP_API_KEY 环境变量是否正确设置")

print(f"账户余额: {balance_info.get('credits', 0)} 条额度")
错误 2：429 Rate Limit - 请求频率超限
报错信息：{"error": "Rate limit exceeded. Retry after 60 seconds"}
原因：批量拉取时请求频率超过 HolySheep Tardis 服务的限流阈值（默认 100次/分钟）。
解决代码：
import time
from ratelimit import limits, sleep_and_retry
@sleep_and_retry
@limits(calls=80, period=60) # 设置每分钟 80 次，留 20% 余量
def throttled_fetch(url, headers, params):

raise Exception("达到最大重试次数")
错误 3：500 Internal Server Error - 交易所数据不可用
报错信息：{"error": "Data not available for the requested time range"}
原因：请求的时间段内目标交易所未开盘（如 Deribit 合约到期）或数据未归档。
解决代码：

回滚方案设计
迁移过程中可能出现 HolySheep 服务不可用的情况，建议保留原有数据获取通道作为降级方案。
# 双通道数据获取器
def fetch_orderbook_dual_channel(exchange, symbol, date):
"""
优先使用 HolySheep，失败时回退到官方 API
需自行配置 TARDIS_API_KEY 官方密钥
"""
# 通道1：HolySheep
try:
result = fetch_binance_orderbook_snapshot(symbol, date)
if result and result.get('data'):
print(f"[HolySheep] {exchange} {symbol} {date} 获取成功")
return {"source": "holysheep", "data": result}
except Exception as e:
print(f"[HolySheep] 失败，尝试备用通道: {e}")
# 通道2：官方 Tardis（降级方案）
try:

return {"source": "official", "data": None}
