Text Analytics API (v3.1-preview.2)
The Text Analytics API is a suite of text analytics web services built with best-in-class Microsoft machine learning algorithms. The API can be used to analyze unstructured text for tasks such as sentiment analysis, key phrase extraction and language detection. No training data is needed to use this API; just bring your text data. This API uses advanced natural language processing techniques to deliver best in class predictions. Further documentation can be found in https://docs.microsoft.com/en-us/azure/cognitive-services/text-analytics/overview
Detect Language
The API returns the detected language and a numeric score between 0 and 1. Scores close to 1 indicate 100% certainty that the identified language is true. See the Supported languages in Text Analytics API for the list of enabled languages.

(optional)
string
(Optional) This value indicates which model will be used for scoring. If a model-version is not specified, the API should default to the latest, non-preview version.
(optional)
boolean
(Optional) if set to true, response will contain input and document level statistics.
Request headers
string
Media type of the body sent to the API.
string
Subscription key which provides access to this API. Found in your Cognitive Services accounts.
Request body
Collection of documents to analyze.
