Frequently asked questions​

How do I specify the source language?​

Set the source field in your request body. If you omit it, Langbly automatically detects the source language and returns it in the detectedSourceLanguage field of the response.

Is a credit card required to get started?​

No. The free tier gives you 500,000 characters per month. No credit card needed.

Can I process data within the EU?​

Yes. Use the EU endpoint eu.langbly.com instead of the global one. The API format and parameters are identical.

How do I translate multiple texts in one request?​

Pass an array of strings as the q parameter instead of a single string. For example: {"q": ["Hello", "Goodbye"], "target": "de"}.
