问题描述

我正在尝试对传统API进行API调用，但出现401错误.以下是其API的链接: https://developer.tradier.com/documentation/markets/get-quotes

I'm trying to make an API call to tradier API, but get 401 error. Here's the link to their API: https://developer.tradier.com/documentation/markets/get-quotes

这是我的简单代码:

library(httr)
tradier <- "https://api.tradier.com/v1/markets/history?symbol=AAPL"
getdata<-GET(url=tradier, add_headers(Authorization="Bearer XXXXXXXXXXXXXXXXX"))
getdata

推荐答案

sandbox API终结点对我有用.我猜想对于brokerage API端点，您必须升级您的帐户.

The sandbox API endpoint works for me. I guess for the brokerage API endpoint you have to upgrade your account.

library(magrittr)
library(httr)

token <- keyring::key_get("tradier_token")
url <- "https://sandbox.tradier.com/v1/markets/quotes?symbols=AAPL,MSFT"
resp <- GET(url = url, add_headers(Authorization = paste("Bearer", token)))
content(resp)[[1]] %>%
  data.table::rbindlist()
