  title: Unbabel Translation Account Word Count API
  description: 'The Unbabel Translation API (tapi/v2) is an asynchronous REST API for the Unbabel Language Operations (LangOps) platform. Callers submit text with a source/target language pair, tone, and topic; Unbabel returns a job identifier (uid) immediately and processes the translation with always-on AI plus optional human review. Results are retrieved by uid, by listing jobs by status, or delivered to a callback URL. The API also exposes a pure machine-translation path (mt_translation) and helper resources for language pairs, tones, topics, word count, and account details.

    Authentication uses a token header of the form `Authorization: ApiKey <username>:<api_key>`. The production base URL is https://api.unbabel.com/tapi/v2 and a sandbox is available at https://sandbox.unbabel.com/tapi/v2. Endpoints for translation, mt_translation, language_pair, tone, topic, account, and wordcount are confirmed from Unbabel''s public developer docs and the official unbabel-py client; the asynchronous callback (webhook) payload is modeled from the documented callback behavior.'
