Endpoint Context Protocol
One URL. Two representations. Your existing site serves humans and agents.
Endpoint Context Protocol (ECP) is a lightweight method for making any existing website agent-friendly by leveraging standard HTTP content negotiation headers. With a few lines of code, the same URL can return human-readable HTML to browsers and clean semantic content to AI agents and LLMs — no new infrastructure or routing required. It also offers an optional hosted context server and a public directory for agent-discoverable site listings.
By inspecting HTTP request headers (Sec-Fetch-Dest and Accept), the server detects whether the caller is a browser or an agent and returns either standard HTML or a clean semantic payload from the same canonical URL.
