Language Detection API

What it does

Language Detection identifies the language of a text sample and returns the result in multiple standard formats. Send a body containing text with at least 50 characters, and get back the detected language, ISO 639-3 code, ISO 639-1 iso_code, script, and a numeric confidence score.

Use Language Detection when you need to route user content, pick the right translation pipeline, or apply language-specific processing in a product workflow. It is useful for content moderation, multilingual support tools, document ingestion, and any system that needs to classify incoming text before taking the next step.

The response is compact and easy to consume in automation. You can store the language label, compare it against expected input, or use the confidence score to decide whether to fall back to manual review or a secondary detector. Because the service returns both human-readable and machine-friendly codes, it fits cleanly into search, tagging, and NLP pipelines.

If you process user-submitted text, feeds, tickets, or documents, Language Detection gives you a straightforward way to identify what language you are dealing with before you translate, index, or analyse it.
