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, GetList and GetSearch.
• 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

quandl's Issues

Update to Quandl API v3

Need to update the library to use Quandl API v3 instead of v1
The v3 api also has a slightly different response structure, so its not only updating the endpoint URLs.

Changes needed:

• Update the endpoint URLs to use v3
• Update the response types accordingly
• Make sure the tests all pass, or modify to pass

If anyone feels like taking a stub at this, I will gladly merge a PR.
