Vertral Spatial Engine — The graph behind a better walk.
Vertral Spatial Engine is the graph and pathfinding core behind Pathways: a multi-level pedestrian network and weighted walk search, running on device today.
Also at /vertral and /spatial-engine — same product.
VERTRAL SPATIAL ENGINE
Path context for builders and agents.
A multi-level pedestrian graph (Hong Kong only for now) and weighted walk search. Pathways uses this on-device today. A hosted API, including agentic MCP through that API, is coming soon.
VSE is the spatial stack. Ionic is a separate product for agent contracts.
Sheltered
Prefer covered connections where available.
Cooled
Lean toward less exposed walking.
Accessible
Prefer mapped accessible connections; check on-site conditions.
On-device now. API and MCP coming soon.
On device · today
Pathways uses the local graph and pathfinding core today.
Hosted API + Agentic MCP · coming soon
Cloudflare Worker endpoints for non-browser clients that need path or context. Coming soon — not generally available. Agentic MCP is delivered via this API.
On-device in Pathways today.
The graph we ship is Hong Kong only for now. The Pathways map plans on a local graph. A hosted Worker API and MCP for non-browser clients are coming soon. When they ship, hosting may keep operational logs for reliability — not a trip dossier.
Meet the engine in motion.
Pathways is where VSE’s local graph becomes a route you can use today.
