apilayer languagelayer vs Google Cloud Natural

languagelayer is apilayer's language-detection API, identifying the source language of arbitrary text across 173 languages in a single REST call with confidence scores. It supports both single-string and batch detection, aimed at content-moderation, routing, and localization pipelines that need to know what language they're dealing with before further processing.

Google Cloud Natural Language analyzes syntax, entities, and sentiment in text using the same machine-learning models that power Google's own products, callable via a straightforward API-key-authenticated REST interface. It includes a free monthly usage tier before per-unit billing applies to higher volumes.
