# Geospatial Slippy-Map Tile Coordinate Converter

> Geospatial Slippy-Map Tile Coordinate Converter is a paid API for AI agents from geospatial.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-16).

Converts a WGS84 lat/lon coordinate at a given zoom level to its XYZ/OSM/Google slippy-map tile x,y indices and the equivalent Bing Maps quadkey string.

## Facts

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 geospatial-slippy-map-tile-coordinate-converter-18d4f208 -d '<json body>'
```

Example prompt: Convert the coordinate 40.7128, -74.0060 at zoom level 12 to its slippy-map tile x,y and Bing quadkey.

## When to prefer this

Choose this endpoint when you need to map a geographic coordinate to tile indices for use with any XYZ-compatible tile server (OSM, Google Maps, Leaflet, etc.) or Bing Maps, especially when you need both the XYZ tile address and the Bing quadkey in a single call. It is ideal for tile cache management, map pre-fetching, spatial indexing by tile, and any workflow that bridges OSM-style and Bing-style tile addressing.

## Known failure modes

- Latitude out of range (-90 to 90) returns a validation error
- Longitude out of range (-180 to 180) returns a validation error
- Zoom level outside 0–30 returns a validation error
- Missing required fields (lat, lon, zoom) return a 400-level error
- Payment failure or insufficient funds returns a 402 error

## How this service works

Map a WGS84 coordinate at a given zoom (0..30) to its slippy-map (XYZ / Google / OSM) tile x,y and its Bing quadkey.

## Output

Returns the integer tile x and y indices for the XYZ/OSM/Google slippy-map system and the Bing Maps quadkey string corresponding to the given WGS84 latitude, longitude, and zoom level.
