  "raw_analysis": "Detect Language is a SaaS platform that provides a simple REST API for language detection. It is designed for developers who need to identify the language of user-generated content, such as comments, emails, or social media posts. The API allows sending text and receiving the detected language code along with a confidence score. It supports multiple languages and offers optional hints to improve accuracy. The service is mature and widely used, with client libraries for major languages. It follows a freemium model: a free tier for limited use, and paid subscriptions for higher volume and commercial use. Authorization is via an API key sent as a Bearer token in the Authorization header. The official documentation is available at https://detectlanguage.com/docs, and pricing details are at https://detectlanguage.com/pricing. Since I don't have access to real-time data, I infer the endpoint structure from common REST patterns and known features. The service likely has rate limits per plan, but exact numbers are not publicly advertised in the given content. The platform integrates with web applications, mobile backends, and content moderation systems. Overall, it is a straightforward, purpose-built API service."
