Amazon Books API

Provides functions to fetch book information from Amazon Products API.

Usage

Add amazon_books to your list of dependencies in mix.exs:

def deps do
  [{:amazon_books, "~> 0.4.0"}]
end

Configure your AWS credentials like this:

config :amazon_books, :associate_tag, "associate-tag"
config :amazon_books, :access_key_id, "your-access-key"
config :amazon_books, :secret_access_key, "your-key"

In production, you might want to load your config from environment variables. For this, you can use the following syntax:

config :amazon_books,
  associate_tag: {:system, "AMAZON_ASSOCIATE_TAG"},
  access_key_id: {:system, "AMAZON_ACCESS_KEY_ID"},
  secret_access_key: {:system, "AMAZON_SECRET_ACCESS_KEY"}

Examples:

# Lookup by ISBN 10 or ASIN
AmazonBooks.lookup("076243631X")

# Search by title or keywords
AmazonBooks.search_by_title("Elixir in Action")
AmazonBooks.search_by_keywords("elixir programming")

# Search within a country (defaults to US)
AmazonBooks.search_by_title("Elixir in Action", %{"country" => "IN"})

# Include additional options
AmazonBooks.lookup("076243631X", %{"Sort" => "relevancerank"})

# Perform custom queries
AmazonBooks.query(%{"Title" => "Harry Potter", "Sort" => "relevancerank"})
