What is Language Detection API?

Language Detection automatically detects the language of any text input, making it a valuable asset in a variety of applications such as Machine Translation, Natural Language Processing (NLP) and Text Analysis. It's as simple as inputting a text string and receiving the detected language code, like "en" for English or "fr" for French. Many companies even offer Language Detection as a convenient API service, easily integratable with other programs.
