How this service works
Un-project Web Mercator (EPSG:3857) easting/northing in metres back to WGS84 longitude/latitude in degrees.
Output
Returns the WGS84 longitude and latitude in decimal degrees corresponding to the input Web Mercator easting (x) and northing (y) in metres, effectively reversing the EPSG:3857 projection.
Example use cases
Decode tile server click coordinates
“A user clicked on my web map at Web Mercator coordinates x=2226389.82, y=4865942.28 — can you convert those back to longitude and latitude so I can look up what's at that location?”
Recover geographic point from GIS database
“Our database stores geometries in EPSG:3857 and I have a point at x=-8235939.40, y=4970241.32 metres — please convert that to WGS84 decimal lat/lon.”
Reverse-engineer map feature location
“I pulled coordinates from a Web Mercator layer: easting 13149614.85, northing 3503549.84 — what are the WGS84 longitude and latitude for that point?”
Technical details
Endpoint
POSThttps://geospatial.openverbs.com/v1/inverseWhen to prefer
Choose this endpoint when you have coordinates already expressed in Web Mercator (EPSG:3857) metres — common output from tile servers, GIS databases, and web mapping libraries — and need to recover human-readable WGS84 decimal degrees. Prefer this over UTM or MGRS converters when the source data is specifically in EPSG:3857 projected metres.
Side effects
- x or y value outside valid range (±20037508.34 metres) returns a validation error
- missing required x or y body fields returns a 400-level error
- non-numeric values for x or y cause schema validation failure
- payment not provided or insufficient USDC results in 402 Payment Required
