What It Is

Every AI agent needs a source of truth, and 4ort.xyz is the lab's: a knowledge graph of ~40 million entities, grounded in Wikidata and published CC0. Every other property in the lab cites it: when an agent in Mission Control answers a question, when the video factory scripts a nature short, when the news brain identifies who a story is about, the facts come from here.

It's not a static dump. A real-time Wikidata edit firehose keeps the graph current, pageview-derived popularity ranking orders entities by what the world is actually paying attention to, and a GDELT-fed "Living Edge" mints brand-new entities within 15 minutes of them appearing in world news, so the graph knows about things before most databases have heard of them.

On top of the graph sits an agentic search engine: natural-language smart routing decides how to answer a query, trending slices expose what's rising across a 33-slug taxonomy, and SSE streaming surfaces push live updates to anything listening.
