Alpaca Trade API：未找到端点？

Question

我正在尝试使用alpaca_trade_api来获取一些历史数据。但是当我这样做时，我收到以下错误：

alpaca_trade_api.rest.APIError：找不到端点

代码是：

import alpaca_trade_api as tradeapi  
import pandas as pd 

# keys
KEY = "XXX"
SECRET = "XXX"

# parameters
short_sma_period = 50 
long_sma_period = 200 

start_date = "2023-01-01"
end_date = "2023-05-01"
timeframe = '1D' # time frame for historical data 

asset = "USD/JPY"

# urls
data_url = "https://data.alpaca.markets"
paper_trade_url = "https://paper-api.alpaca.markets"

# initialize apis
data_api = tradeapi.REST(key_id=KEY,secret_key=SECRET,base_url=data_url, api_version="v2")
trade_api = tradeapi.REST(key_id=KEY,secret_key=SECRET,base_url=paper_trade_url)

# get historical data 
historical_data = data_api.get_bars(asset, timeframe, start=start_date, end=end_date)

截至 2023 年，Alpaca Markets 仅支持美国股票和 ETF 以及加密货币。使用其他经纪商交易代码中引用的货币对，例如

USD/JPY

。
