Translate Many Languages

Translation API supports more than one hundred different languages, from Afrikaans to Zulu. Used in combination, this enables translation between thousands of language pairs.

Language Detection

Sometimes you don’t know your source text language in advance. For example, user generated content might not contain a language code. Translation API can automatically identify languages with high accuracy.

Simple Integration

Translation API is an easy to use Google REST API. You don’t have to extract text from your document, just send it HTML documents and get back translated text.

Highly Scalable

Translation API can seamlessly scale with almost any volume. We provide a generous daily quota and allow you to set limits below that amount. If a higher quota is needed, you can simply request an increase.

Simple, Affordable Pricing

Translation API charges on a per character basis, even if the character is multiple bytes. Our prices are affordable, making Translation API a low cost localization solution compared to alternative methods.
