What does simfinapi do?

simfinapi wraps the https://www.simfin.com/ Web-API to make ‘SimFin’ data easily available in R.

To use the package, you need to register at https://app.simfin.com/login and obtain a ‘SimFin’ API key.

Example

In this example, we download some stock price data and turn these into a simple plot.

# load package
# library(simfinapi)
devtools::load_all()
#> ℹ Loading simfinapi

# download stock price data
tickers <- c("AMZN", "GOOG") # Amazon, Google
prices <- sfa_load_shareprices(tickers)

Please note that all functions in simfinapi start with the prefix sfa_. This makes it easy to find all available functionality.

The downloaded data looks like this:

Let’s turn that into a simple plot.

# load ggplot2
library(ggplot2)

# create plot
ggplot(prices) +
  aes(x = Date, y = `Last Closing Price`, color = name) +
  geom_line()

Installation

From CRAN:

install.packages("simfinapi")

If you want to try out the newest features you may want to give the development version a try and install it from GitHub:

remotes::install_github("https://github.com/matthiasgomolka/simfinapi")

Setup

Using simfinapi is much more convenient if you set your API key and cache directory¹ globally before you start downloading data. See ?sfa_set_api_key and ?sfa_set_cache_dir for details.
