  title: Weglot Translation Languages API
  description: REST API for the Weglot website translation platform. The /translate endpoint translates an array of sentences from a source language to a target language and is authenticated with an api_key query parameter. The public /public/* endpoints expose the catalog of supported languages, a language-pair support check, and a health-check status endpoint, and require no authentication. This is the same translation service consumed by the Weglot JavaScript, WordPress, Shopify, and CMS integrations.
