Endpoint Context Protocol

The product is a developer infrastructure layer that uses HTTP content negotiation to serve clean semantic markdown to AI agents and HTML to browsers from the same URL, making existing websites readable and actionable for automated clients without new routing, subdomains, or infrastructure. It sells to software developers and engineering teams responsible for business websites that need agent discovery. It is positioned as using the existing web standard as intended rather than adding a new protocol or app layer on top of the web.
