Acceptable use

You may use EngtoSpan for any lawful purpose. You may not use it to process illegal content, to attempt to overload the service, or to resell output as a competing translation API without a Business plan.

Accuracy

Machine translation is highly accurate but not infallible. For legally binding, medical or safety-critical documents, always have output reviewed by a qualified human translator.

Availability

We aim for 99.9% uptime but provide the free service on an as-is basis.

API terms

API access is subject to the rate limits and quotas of your plan. Keys may be revoked for abuse.
