Go library for accessing Quandl API
Go Quandl
This library provides easy access to the Quandl API using the Go programming language.
The full documentation is at:
godoc.org/github.com/DannyBen/quandl
Install
$ go get github.com/DannyBen/quandl
Features
- Supports 3 call types to Quandl:
GetSymbol,GetListandGetSearch. - Returns either a native Go object, or a raw (CSV/JSON/XML) response.
- Built in cache handling.
Usage
Basic usage looks like this:
quandl.APIKey = "YOUR KEY"
data, err := quandl.GetSymbol("WIKI/AAPL", nil)
and will return a native Go object. To use the data in the response, iterate through its Data property:
for i, item := range data.Data {
fmt.Println(i, item[0], item[2])
}
To receive a raw response from Quandl (CSV, JSON, XML) you can use:
data, err := quandl.GetSymbolRaw("WIKI/AAPL", "csv", nil)
To pass options to the Quandl API, use something like this:
v := quandl.Options{}
v.Set("trim_start", "2014-01-01")
v.Set("trim_end", "2014-02-02")
data, err := quandl.GetSymbol("WIKI/AAPL", v)
More examples are in the quandl_test file or in the official godoc documentation
Development
Before running tests, set your API key in an environment variable.
$ export QUANDL_KEY=your_key_here
$ go test -v
