100% compatible with: Google Translate v2 API, googletrans Python library, any library using the translate.googleapis.com endpoint format.

Code Examples

cURL — Translate Text

# SocketsIO (same format as Google Translate v2)
curl "https://api.socketsio.com/v1/translate" \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"q": "Hello, world!", "target": "es", "source": "en"}'

# Response:
# {"translations": [{"translatedText": "¡Hola, mundo!", "detectedSourceLanguage": "en"}]}

Python — Before (Google Translate)

from google.cloud import translate_v2 as translate

client = translate.Client()
result = client.translate("Hello, world!", target_language="es")
print(result["translatedText"])  # ¡Hola, mundo!

Python — After (SocketsIO, drop-in replacement)

import requests

def translate(text, target, source="auto"):
    resp = requests.post(
        "https://api.socketsio.com/v1/translate",
        headers={"X-API-Key": "YOUR_API_KEY"},
        json={"q": text, "target": target, "source": source}
    )
    return resp.json()["translations"][0]["translatedText"]

print(translate("Hello, world!", "es"))  # ¡Hola, mundo!

JavaScript / Node.js

// Before: @google-cloud/translate (requires GCP credentials)
// After: SocketsIO (just an API key)

const translate = async (text, target) => {
  const res = await fetch("https://api.socketsio.com/v1/translate", {
    method: "POST",
    headers: {
      "X-API-Key": "YOUR_API_KEY",
      "Content-Type": "application/json"
    },
    body: JSON.stringify({ q: text, target, source: "auto" })
  });
  const data = await res.json();
  return data.translations[0].translatedText;
};

translate("Hello, world!", "ja").then(console.log); // こんにちは、世界！
