# Google Maps 3D Tiles Root JSON

> Google Maps 3D Tiles Root JSON is a paid API for AI agents from Google Maps at googlemaps.mpp.tempo.xyz, paid per call via MPP, $0.017/call, status unknown (last checked 2026-10-11).

Returns the root tileset JSON descriptor for Google Maps 3D tiles, enabling initialization of a 3D tile streaming session.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability google-maps-root-json-a4d19b7e
```

Example prompt: Can you fetch the root tileset JSON from Google Maps 3D Tiles so I can initialize a photorealistic 3D globe rendering session?

## When to prefer this

Use this endpoint when you need to initialize a 3D tile rendering pipeline using Google Maps photorealistic 3D tiles. This is the entry point for any 3D tile streaming workflow — call it after obtaining a session via CreateSession. Prefer this over static map or 2D tile endpoints when you need full 3D scene geometry for visualization, AR, or simulation purposes.

## Known failure modes

- Missing or invalid session token returns 401 Unauthorized
- Expired tile session returns 403 Forbidden requiring a new CreateSession call
- Rate limiting returns 429 Too Many Requests
- Network timeout if tile servers are unreachable
- Malformed session parameters return 400 Bad Request

## How this service works

Get 3D tiles root

## Output

A JSON object conforming to the 3D Tiles specification, containing the root tileset descriptor with bounding volume, geometric error, refine strategy, and child tile references needed to begin streaming and rendering 3D map tiles.
