agenticweb.wiki is a reference for the standards that let software agents use the web: how an agent finds what a site offers, proves who it is, learns what it may do, reads, acts, coordinates with other agents, pays, shows a person the result, and is held to account. Each article is written from the primary specification with a numbered reference for every claim.

Every article is served three ways at one address: HTML, Markdown and JSON. The dataset is on the data page, indexed in llms.txt, and declared in the ARD manifest, which also lists the MCP server.
