Batch API

Each Indico method has a corresponding batch method for analyzing many examples with a single request. Simply pass in an array of inputs and receive an array of results in return.

> require 'indico'

=> true

> Indico.api_key = "YOUR_API_KEY"

=> "YOUR_API_KEY"

> Indico.sentiment(['Best day ever', 'Worst day ever'])

=> [0.9899001220871786, 0.005709885173415242]

Calling multiple APIs with a single function

There are two multiple API functions analyze_text and analyze_image (and their batch counterparts). These functions are similar to the existing api functions, but take in an additional apis argument as an array of strings of API names (defaults to all existing apis). analyze_text accepts a list of existing text APIs and vice versa for analyze_image.

Accepted text API names: text_tags, political, sentiment, language

Accepted image API names: fer, facial_features, image_features
