alphavantager: A lightweight R interface to the Alpha Vantage API
Description
A lightweight R interface to the Alpha Vantage API
Details
The alphavantager
package provides a lightweight interface to the
Alpha Vantage API. Alpha Vantage is a free source for financial data
that in many cases is more accurate than Yahoo Finance and Google Finance.
Get a free API KEY at https://www.alphavantage.co. Then use the R interface
functions av_api_key("YOUR_KEY")
to set the API key and the av_get()
function to get financial data.
Set the Alpha Vantage API Key
Description
Set the Alpha Vantage API Key
Usage
av_api_key(api_key)
Arguments
api_key |
A character string with your Alpha Vantage API Key. |
Details
The Alpha Vantage API key must be set prior to using av_get()
. You can obtain
an API key at the Alpha Vantage Website.
Value
Invisibly returns API key once set. Use print method to view.

Examples
## Not run:
av_api_key("YOUR_API_KEY")
av_get(symbol = "MSFT", av_fun = "TIME_SERIES_INTRADAY", interval = "15min", outputsize = "full")
## End(Not run)
Get financial data from the Alpha Vantage API
Description
Get financial data from the Alpha Vantage API
Usage
av_get(symbol, av_fun, ...)
Arguments
symbol |
A character string of an appropriate stock or fund. See parameter "symbol" in Alpha Vantage API documentation. |
av_fun |
A character string matching an appropriate Alpha Vantage "function". See parameter "function" in Alpha Vantage API documentation. |
... |
Additional parameters passed to the Alpha Vantage API. For a list of parameters, visit the Alpha Vantage API documentation. |
Details
The av_fun
argument replaces the API parameter “function” because function is a reserved name in R. All other arguments match the Alpha Vantage API parameters.
There is no need to specify the apikey
parameter as an argument to av_get(). The required method is to set the API key using av_api_key("YOUR_API_KEY").
There is no need to specify the datatype parameter as an argument to av_get(). The function will return a tibble data frame.
Some data sets only return 100 rows by default. Change the parameter outputsize = "full"
to get the full dataset.
Get more than one symbol. The Alpha Vantage API is setup to return one symbol
per API call. Use the tidyquant::tq_get()
API to get multiple symbols.
ForEx "FROM/TO" symbol details. FOREX symbols in the av_get()
function are
supplied in "FROM/TO"
format, which are then parsed in the Alpha Vantage API
into from_currency
and to_currency
API parameters. Usage example:
av_get(symbol = "EUR/USD", av_fun = "FX_DAILY")
Value
Returns a tibble of financial data
