The Valr API gem allows you to interact with the VALR cryptocurrency exchange API from your Ruby applications.

Install the gem and add to the application's Gemfile by executing:

bundle add valr_api

Or add the following to your Gemfile:

gem 'valr_api', '~> 0.2.1'

Then execute:

bundle install

If bundler is not being used to manage dependencies, install the gem by executing:

gem install valr_api

Before using the gem, you need to initialize a client with your VALR API key and secret.

client = ValrApi::Client.new("your_api_key", "your_api_secret")

After initializing the client, you can send GET, POST, and DELETE requests to the VALR API. I am still working on allowing requests to the websocket API.

Here are some sample requests:

# GET request
response = client.get("/public/currencies")

# POST request
response = client.post("/orders/limit", {
  "side": "SELL",
  "quantity": "0.100000",
  "price": "10000",
  "pair": "BTCZAR",
  "postOnly": true,
  "customerOrderId": "1235"
})

# DELETE request
response = client.delete("/orders/order")

Check if a request was successful (assuming you have assigned the response to a variable called response):

response.success?

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install.
