Or install it yourself as:
$ gem install alchemy-api-rb
You'll need to request an API Key.
Set your API Key in an initializer or something similar:
AlchemyAPI.key = "xxxxxxxxxxxxxxxxxx"You may set the key along with other config settings:
AlchemyAPI.configure do |config|
config.apikey = "xxxxxxxxxxxxxxxxxx"
config.output_mode = :xml # not yet supported
endRequest keyword extraction for a string of text:
results = AlchemyAPI.search(:keyword_extraction, text: "hello world")or
results = AlchemyAPI::KeywordExtraction.new.search(url: 'http://www.alchemyapi.com/')or
results = AlchemyAPI::KeywordExtraction.new.search(html: "<html><body>lorem ipsum</body></html>")Results for keyword extraction are returned as a array of keywords:
[
{
"text" => 'lorem ipsum',
"relevance" => "0.993164"
}
]The specs are expecting your API Key as an environment variable named ALCHEMY_API_KEY. You can export it locally or prepend the test command like so:
ALCHEMY_API_KEY="this-is-my-40-character-key" bundle exec rake test
If you would like to expirement with the API you can run the console rake task and use the commands above to set the API Key issue search commands:
bundle exec rake console
- Add missing Alchmey API search modes
- Add support for raw output (JSON, XML and RDF)?
