No. Langbly is an independent company. We offer a Google Translate v2-compatible API, which means you can switch from Google Translate by changing a single endpoint URL. No code changes required.
We support over 100 languages, including all major European, Asian, and Middle Eastern languages. Check our documentation for the full list, or send a test request to see if your language pair is supported.
Langbly uses context-aware translation that understands full sentences, not just individual words. For most language pairs, quality is comparable to or better than traditional machine translation services. We recommend testing with your own content to judge the results yourself.
Billing is based on the number of input characters you send (the "q" parameter). Everyone gets 500K characters per month for free. Above that, usage costs $5 per 1M characters. You only get charged when your accumulated balance reaches $5. If your balance stays under $5, it carries over to the next month.
Without a payment method, your API stops at 500K characters per month. With a payment method, usage above 500K is billed at $5 per 1M characters. There are no hard limits. You only get charged when your balance reaches $5.
Add a payment method anytime from the billing page in your dashboard. To cancel, use the Stripe billing portal (accessible from the billing page). Your 500K free characters per month remain available regardless.
Yes. Enterprise plans come with custom volumes, dedicated support, and SLA guarantees. Contact us through the contact form and we will put together a proposal.
Each request can contain up to 50 text strings and 10,000 input characters total. Requests have a 20-second timeout. There are no monthly request count limits. If you need higher per-request limits, contact us.
Yes. You can send multiple text strings in a single request using the "q" parameter as an array. This is more efficient than making separate requests and counts as a single API call.
Yes. Official SDKs for Python (PyPI) and JavaScript/TypeScript (npm) are available. Both include auto-retry, typed errors, and Retry-After support. You can also use the REST API directly from any language.
Yes. All traffic is encrypted with TLS 1.3. Translation content exists only in memory during processing and is discarded immediately after the response is sent. We never store, log, or cache your translation text. The only data we keep is your account information and aggregated usage counts for billing.
No. Your translation content is never used to train, fine-tune, or improve any model. This is a permanent commitment.
You can create, rotate, and revoke API keys from your dashboard at any time. Each key is verified on every request. You can have multiple active keys per account.
Yes. Our dedicated EU endpoint (eu.langbly.com) processes everything in the Netherlands. Data never leaves the European Union. See our security page for details.
