Language Detector

Overview

Language Detector works by analyzing the text and comparing it to a database of languages and ai models. It uses advanced algorithms to detect the language of the text and returns the language code and the confidence level.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

curl -X POST https://api.apiverve.com/v1/languagedetector \
  -H "x-api-key: your_api_key_here" \
  -H "Content-Type: application/json" \
  -d '{
  "text": "esta es una frase en español. esta API puede detectar fácilmente el idioma"
}'

const res = await fetch('https://api.apiverve.com/v1/languagedetector', {
  method: 'POST',
  headers: {
    'x-api-key': 'your_api_key_here',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
  "text": "esta es una frase en español. esta API puede detectar fácilmente el idioma"
}),
});

if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);

const { data } = await res.json();
console.log(data);

import requests

res = requests.post(
    "https://api.apiverve.com/v1/languagedetector",
    headers={"x-api-key": "your_api_key_here"},
    json={
    "text": "esta es una frase en español. esta API puede detectar fácilmente el idioma"
},
    timeout=15,
)
res.raise_for_status()

print(res.json()["data"])

package main

import (
	"fmt"
	"io"
	"net/http"
	"strings"
)

func main() {
	body := strings.NewReader(`{
  "text": "esta es una frase en español. esta API puede detectar fácilmente el idioma"
}`)
	req, _ := http.NewRequest("POST", "https://api.apiverve.com/v1/languagedetector", body)
	req.Header.Set("Content-Type", "application/json")
	req.Header.Set("x-api-key", "your_api_key_here")

	res, err := http.DefaultClient.Do(req)
	if err != nil {
		panic(err)
	}
	defer res.Body.Close()

	out, _ := io.ReadAll(res.Body)
	fmt.Println(string(out))
}

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

Parameters

Sent as JSON in the request body. Premium parameters are accepted on every plan but only take effect on plans that include them.

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

{
  "status": "ok",
  "error": null,
  "data": {
    "primaryLanguage": "spanish",
    "primaryCode": "es",
    "confidenceLevel": "medium",
    "detectedLanguages": [
      {
        "language": "spanish",
        "confidence": 0.38471794871794873,
        "code": "es"
      },
      {
        "language": "portuguese",
        "confidence": 0.2946153846153846,
        "code": "pt"
      },
      {
        "language": "danish",
        "confidence": 0.2464615384615384,
        "code": "da"
      }
    ]
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

Use cases

Content Moderation

Use the Language Detector API to detect the language of text for content moderation. Use the data to filter out inappropriate content and maintain community standards

Multilingual Support

Detect languages by using the Language Detector API to support multilingual content. Use the data to provide language-specific features, translations, and user experiences

Text Analysis

Analyze text by using the Language Detector API to detect the language of text. Use the data to study language patterns, sentiment analysis, and text classification
