Fetching book info from Google Books API using elixir

google_books.ex

defmodule GoogleBooks do
  use HTTPoison.Base

  @base_url "https://www.googleapis.com/books/v1/volumes?q=isbn:"

  def process_url(isbn13) do
    isbn = String.replace(isbn13, "-", "")
    @base_url <> isbn
  end

  def process_response_body(body) do
    body
    |> Poison.decode!
    |> Enum.map(fn({k, v}) -> {String.to_atom(k), v} end)
  end
end

...and exchange @base_url for "http://libris.kb.se/xsearch?format=json&query=ISBN:" to look stuff up on LIBRIS :)
