The apilayer languagelayer API provides language detection capabilities for text in 173 different languages. It is designed to help developers identify the language of any given text input through a simple JSON-based API.

This API is useful for applications that need to process multilingual content, such as content filtering, analytics, or user experience customization based on language. The use of OAuth authentication ensures secure access to the API.

Developers integrating this API can easily add language detection features to their applications without managing complex language models or datasets, relying instead on the API's broad language support and straightforward interface.
