The API.AI ruby gem

A Ruby SDK to the https://api.ai natural language processing service.

Installation

gem install api-ai-ruby

Basic Usage

Just pass correct credentials to ApiAiRuby::Client constructor

client = ApiAiRuby::Client.new(
    :client_access_token => 'YOUR_CLIENT_ACCESS_TOKEN'
)

After that you can send text requests to the https://api.ai with command

response = client.text_request 'hello!'

And voice requests with file stream

file = File.new 'hello.wav'
response = client.voice_request(file)

Example answer:

{
  :id        => "6daf5ab7-276c-43ad-a32d-bf6831918492",
  :timestamp => "2015-12-22T08:42:15.785Z",
  :result    => {
    :source        => "agent",
    :resolvedQuery => "Hello",
    :speech        => "Hi! How are you?",
    :action        => "greeting",
    :parameters    => {},
    :contexts      => [],
    :metadata      => {
      :intentId   => "a5d685ab-1f19-46b0-9478-69f794553668",
      :intentName => "hello"
    }
  },
  :status    => {
    :code      => 200,
    :errorType => "success"
  }
}

voice_request and text_request methods returns symbolized https://api.ai response. Structure of response can be found at https://docs.api.ai/docs/query#response.

Advanced usage

During client instantiating you can additionally set parameters like api url, request language and version (more info at https://docs.api.ai/docs/versioning, https://docs.api.ai/docs/languages)

ApiAiRuby::Client.new(
    client_access_token: 'YOUR_ACCESS_TOKEN',
    api_lang: 'FR',
    api_base_url: 'http://example.com/v1/',
    api_version: 'YYYYMMDD'
)

And you also can send additional data to server during request, use second parameter of text_request and voice_request methods to do that

    response = client.text_request 'Hello', :contexts => ['firstContext'], :resetContexts => true
    response = client.voice_request file, :timezone => "America/New_York"

More information about possible parameters can be found at https://docs.api.ai/docs/query page

#Error handling ApiAiRuby::Client currently able to raise two kind of errors: ApiAiRuby::ClientError (due to configuration mismatch) and ApiAiRuby::RequestError in case of something goes wrong during request. For both kind of errors you can get error.message (as usual) and ApiAiRuby::RequestError can additionally give you code of server error (you can get it with error.code)
