Migrate from Google Translate v2 to Langbly

Langbly is a drop-in replacement for the Google Translate v2 API. Same request format, same response shape.

The 2-Line Change

Python

# Before
from google.cloud import translate_v2 as translate
client = translate.Client()

# After
from langbly import Langbly
client = Langbly(api_key="your-langbly-key")

JavaScript

// Before
import { Translate } from "@google-cloud/translate/build/src/v2";
const client = new Translate();

// After
import { Langbly } from "langbly";
const client = new Langbly({ apiKey: "your-langbly-key" });

cURL / raw HTTP

# Before
POST https://translation.googleapis.com/language/translate/v2?key=GOOGLE_KEY

# After
POST https://api.langbly.com/language/translate/v2
Authorization: Bearer LANGBLY_KEY

The request body and response format are identical.

What stays the same

• Request body format (q, target, source, format)
• Response format (data.translations[].translatedText)
• Language codes (ISO 639-1)
• HTML mode (format: "html")
• Batch requests (array of q values)
• Language detection endpoint
