Categories, use cases, target audiences, pricing types and platforms with live counts and ready-made filter URLs.
One call returns every dimension you can filter products on. Each entry carries an api_url that is already the correct /products query, so an agent can go from “show me marketing tools” to a filtered list in two requests. Cached for ten minutes.

}Products that ship their own MCP server or API
platform=mcp and platform=api filter to products whose founders declared an MCP endpoint or API docs. Handy when an agent is asked for tools it can itself integrate with.
