  "raw_analysis": "languagelayer is a language detection REST API provided by apilayer, a known API marketplace. It allows developers to detect the language of a given text among 173 languages. The service is simple, offering a single endpoint /api/v1/detect that accepts text as a query parameter and returns a JSON with detected language code, confidence, and optional echo of the query. Authentication is via an API key sent as 'access_key' in the query string. It uses a freemium model with a free tier of 100 requests per month, and paid plans with higher limits. The platform is mature as part of the apilayer family, which includes other similar APIs. It offers a dashboard for user management, status page for monitoring, and documentation. Pricing details are available on the site, but specific monthly request limits for paid tiers are not clearly specified in the initial info; typical apilayer plans range from 10k-100k+ requests per month. Integration is straightforward for backend or frontend applications, and it supports multiple languages and use cases like content moderation, localization, and analytics."
