## About

## What it does
Language Detector identifies the language of a text string and returns the most likely ISO 639-1 code plus a probability breakdown for candidate languages.

Send `text` in the request body and get back a `detected` value for the primary language, along with `probabilities` for the languages the model considered. The input text is limited to 512 characters, so it fits short messages, snippets, comments, or user-generated content.

Use Language Detector when you need to route support tickets, pick a translation workflow, choose the right NLP model, or apply language-specific rules before processing content. Because the response includes per-language probabilities, you can inspect borderline cases instead of relying only on a single label.

The API is a good fit for systems that ingest mixed-language text and need a lightweight classification step before search, moderation, analytics, or translation.
