Map Tile Bounds Calculator
x402
Map Tile Bounds Calculator is a paid API for AI agents from map-tiles.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).
Returns the latitude/longitude bounds, EPSG:3857 metre bounds, centre coordinates, and ground size of a slippy-map tile identified by x, y, and zoom level.

How this service works
Latitude/longitude and EPSG:3857 metre bounds of a slippy-map tile x/y/z, with its centre and ground size.
Output
A JSON object containing the tile's north, south, east, and west latitude/longitude bounds; EPSG:3857 minX, minY, maxX, maxY metre bounds; centre latitude and longitude; tile width in EPSG:3857 metres; and the total world width in EPSG:3857 metres at that zoom level. Also echoes back the input x, y, and zoom values.
Example use cases
Validate tile coverage area
“I need to verify which geographic region is covered by tile x=2048, y=1365, zoom=12 — can you give me its north/south/east/west lat/lon bounds and the EPSG:3857 bounding box?”
Centre a map on a tile
“What are the centre latitude and longitude of map tile x=500, y=300, zoom=10 so I can pan my map to that tile?”
Estimate tile ground size
“How wide is tile x=256, y=170, zoom=9 in metres on the ground, using the EPSG:3857 projection?”
Technical details
Endpoint
GEThttps://map-tiles.x402tookit.com/tile-bounds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the precise geographic bounding box or Web Mercator metre bounds of a specific slippy-map tile identified by its x/y/z coordinates. It is the right choice for rendering tile overlays, validating tile coverage, computing tile centres, or passing tile bounds to downstream geospatial operations. Prefer it over manual trigonometry when working with XYZ tile schemes (OpenStreetMap, Google Maps, Mapbox style).
Side effects
- Missing required query parameter (x, y, or zoom) returns an error
- Zoom level out of range 0–24 may return an error or unexpected result
- x or y values outside the valid range for the given zoom (0 to 2^zoom - 1) may return null or error values
- Non-integer values for x, y, or zoom will fail schema validation
- Payment failure (402) if USDC payment header is missing or insufficient
