Detect Language

Overview

Detect Language identifies the language of text — 160+ languages with confidence scores. Auth is a free API key (an invalid key returns 401 with {"error":{"code":1,"message":"Invalid API key"}} — verified).

Quick Start

Detect (replace YOUR_KEY):

curl "https://ws.detectlanguage.com/0.2/detect?q=hello+world" \
  -H "Authorization: Bearer YOUR_KEY"

{
  "data": {
    "detections": [ { "language": "en", "isReliable": true, "confidence": 99.8 } ]
  }
}

With text in the body:

curl -X POST "https://ws.detectlanguage.com/0.2/detect" \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"q": "Bonjour le monde"}'
