What this is

The AI Tools Index is a browsable index of live AI tools organized by category, including tools currently for sale. Every listing links to the maker's real product, and any paid placement is always labeled "Sponsored." This page is the public API documentation for The AI Tools Index. There is no private REST catalog. Agents query live listings through MCP and the documents listed below.
