  "raw_analysis": "SecurityTrails is a mature commercial platform providing comprehensive internet asset intelligence, focusing on domain and IP data. It is designed for security teams, threat hunters, and researchers who need historical and current WHOIS, DNS, SSL, and open port data. The platform is part of Recorded Future, indicating strong backing and integration. The API is well-documented (available at https://securitytrails.com/corp/apidocs) with an API key authentication method, making it easy to integrate programmatically. It offers a freemium model with a limited free tier for evaluation, while paid plans scale with monthly request quotas.
