Complete set · 4 capabilities

The complete GSI capability set.

These are the exact actions your AI can choose when you ask it to work with GSI.

Capability set01 / 01

01-04

4 capabilities in this set.

Part of 4 available through GSI.

  1. 01

    Get location elevation profile

    Points without DEM data return null elevation. Get elevations for up to 25 coordinates at once (elevation profile for a route or area)

  2. 02

    Get elevation

    Coordinates: lon 120-150 (e.g. 139.69 Tokyo), lat 30-46 (e.g. 35.69). Returns null elevation for water or unmeasured points. useful for terrain analysis, flood/hiking checks, geology. Get the official elevation of any point in Japan (GSI 1m/5m/10m laser DEM)

  3. 03

    Geocode address

    G. 東京都千代田区, 東京タワー, 札幌市): coordinates [lon, lat], display title and address code. Accepts partial names. broader terms return multiple candidate areas ranked by the GSI matcher. Japanese input strongly recommended. Geocode a Japanese address or place name to coordinates (official GSI search)

  4. 04

    Compare places terrain

    Returns name, coordinates, elevation and DEM source. quick way to answer "how high is X vs Y" without juggling capabilities. Compare multiple places: geocode each name then fetch its elevation in one call

One connector, every AI

GSI works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put GSI to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 4 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of GSI, so you can see the experience inside your AI.

It does not authenticate your account with GSI. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions GSI owners ask.

  • 01

    Do I need an API key or registration?

    No. Both the GSI elevation service and the address search are public endpoints. no key, no registration. Keep request rates reasonable and they work indefinitely.

  • 02

    Why does elevation sometimes return null?

    Points on water, or outside areas covered by the current DEM grids (some remote islands), have no elevation value. The response also tells you which DEM layer served the value (1m laser, 5m or 10m), so you can judge precision.
