Test and deploy

5 minutes

See the difference

The only change is the base URL and your API key. Everything else stays exactly the same.

Before (Google)
import requests

response = requests.post(
    "https://translation.googleapis.com/language/translate/v2",
    headers={"Authorization": "Bearer GOOGLE_TOKEN"},
    json={"q": "Hello world", "target": "nl"}
)
After (Langbly)
import requests

response = requests.post(
    "https://api.langbly.com/language/translate/v2",
    headers={"Authorization": "Bearer YOUR_API_KEY"},
    json={"q": "Hello world", "target": "nl"}
)

Same request format. Same response format. Just change the URL and key.
