# WITAN Markets

> Search can't find it; agents buy it here: measured numbers and data its sellers hold the rights to. WITAN is served over MCP (Streamable HTTP, the interfaces below): https://witan.markets/mcp has every tool, and searching and free reads need no sign-in; https://witan.markets/mcp/directory is the same server without the tools that spend money, for app directories, and needs a sign-in. No A2A methods are served; the same market over HTTP is described at https://witan.markets/openapi.json.
