## Services

- [Map Tile Maths – Zoom for Extent](https://www.zero.xyz/c/map-tile-maths-zoom-for-extent-f87dd0fe/llms.txt): $0.02/call via x402. Calculates the highest slippy-map zoom level at which a lat/lon bounding box fits inside a given pixel viewport, returning the optimal zoom, map centre, and tile span.
- [Map Tile Maths: Coordinate to Tile (tile-from-coord)](https://www.zero.xyz/c/map-tile-maths-coordinate-to-tile-tile-from-coord-c1a1f062/llms.txt): $0.02/call via x402. Returns the slippy-map tile x/y/z that contains a given latitude/longitude at a specified zoom level, plus the pixel position within the 256 px tile.
- [Map Tile Bounds Calculator](https://www.zero.xyz/c/map-tile-bounds-calculator-05d58796/llms.txt): $0.02/call via x402. 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.
- [Map Tile Maths – Mercator Projection (lat/lon ↔ EPSG:3857 metres)](https://www.zero.xyz/c/map-tile-maths-mercator-projection-lat-lon-epsg-3857-metres-ade008bf/llms.txt): $0.02/call via x402. Converts latitude/longitude coordinates to Web Mercator EPSG:3857 metre coordinates (or vice versa), returning scale distortion factors at the given location.
- [Map Tile Ground Resolution Calculator](https://www.zero.xyz/c/map-tile-ground-resolution-calculator-e22418fd/llms.txt): $0.02/call via x402. Returns metres per pixel, map scale denominator, and tile width on the ground for a given zoom level and latitude.
- [Map Tile Count & Storage Estimator](https://www.zero.xyz/c/map-tile-count-storage-estimator-7932c22e/llms.txt): $0.02/call via x402. Counts the number of slippy-map tiles covering a lat/lon bounding box across a zoom range and estimates storage requirements at a given average tile size.
- [Map Tile Maths – Zoom Level Table](https://www.zero.xyz/c/map-tile-maths-zoom-level-table-dc618b37/llms.txt): $0.02/call via x402. Returns a table of Web Mercator zoom levels (0–24) with tiles per side, metres per pixel, map scale denominator, tile width in metres, total tile count, and typical use, all computed at a chosen latitude.
- [Map Tile Quadkey Converter](https://www.zero.xyz/c/map-tile-quadkey-converter-8097c602/llms.txt): $0.02/call via x402. Converts a slippy-map tile x/y/z to a Bing Maps quadkey, or a quadkey back to x/y/z, returning the parent quadkey and four child quadkeys.

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