Google Cloud Translation API

The Google Cloud Translation API provides programmatic access to Google's neural machine translation technology. It enables developers to dynamically translate text between thousands of language pairs, detect the source language of text, and retrieve lists of supported languages. The API supports both basic (v2) and advanced (v3) translation capabilities including batch translation, custom models, glossaries, and adaptive translation.

Google Cloud Translation API publishes 3 APIs on the APIs.io network: Detections API, Languages API, and Translations API. Tagged areas include Google Cloud, Internationalization, Language Detection, Localization, and Machine Translation.

The Google Cloud Translation API catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Google Cloud Translation API’s developer surface includes developer portal, getting-started guide, documentation, authentication, pricing, support, engineering blog, and 10 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/google-translate: open an issue to ask a question, or submit a pull request to add artifacts.
