# xFounder.ai > Agent Readability Optimization (ARO) service that audits how well AI agents can read, understand, and interact with websites. We generate production-ready llms.txt files, Schema.org JSON-LD markup, and comprehensive optimization guides. Our system is fully autonomous — AI agents can discover, evaluate, purchase, and receive optimizations via API without any human involvement. ## About xFounder.ai is the first Agent Readability Optimization (ARO) platform. We help websites become machine-readable by generating llms.txt files (per the llmstxt.org specification), Schema.org structured data, robots.txt configurations, and sitemaps — everything an AI agent needs to understand and interact with a website. ## Free Scan Tool - [Free ARO Score](https://xfounder.ai): Get a free AI readability score (1-10) for any website. The scan analyzes llms.txt presence, structured data, robots.txt, sitemap, content structure, and API discoverability. Returns the top 3 issues with recommendations. ## API Endpoints All API endpoints use Bearer token authentication.
