x402
WGS84 to Web Mercator (EPSG:3857) Forward Projection is a paid API for AI agents from geospatial.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).
Converts a WGS84 longitude/latitude coordinate pair (in degrees) to Web Mercator (EPSG:3857) easting and northing values in metres.

How this service works
Project WGS84 longitude/latitude (degrees) to Web Mercator (EPSG:3857) easting/northing in metres. Latitude is clamped to ±85.0511° (the projection's valid extent).
Output
Returns the projected easting (X) and northing (Y) values in metres in the EPSG:3857 Web Mercator coordinate reference system. Latitude is clamped to ±85.0511° if the input exceeds the valid projection extent.
Example use cases
Tile layer overlay alignment
“I need to overlay my GPS waypoints onto an OpenStreetMap tile layer — can you project longitude -0.1276 and latitude 51.5074 into Web Mercator easting and northing so the positions line up correctly?”
GIS pipeline coordinate reprojection
“Our GIS pipeline stores features in WGS84, but the rendering engine expects EPSG:3857. Can you reproject longitude 2.3522 and latitude 48.8566 to Web Mercator metres for me?”
Distance calculation in projected space
“I need to work in a Cartesian coordinate space for some planar geometry calculations — please convert longitude 139.6917 and latitude 35.6895 to Web Mercator easting and northing in metres.”
Technical details
Endpoint
POSThttps://geospatial.openverbs.com/v1/forwardWhen to prefer
Use this endpoint when you need to convert WGS84 decimal-degree coordinates into the Web Mercator (EPSG:3857) projected coordinate system used by most web tile mapping services (OSM, Google Maps, Mapbox). Prefer this over a generic GIS library call when running in a serverless or agent context without local geospatial dependencies. Choose the sibling inverse endpoint when going from EPSG:3857 back to WGS84.
Side effects
- Longitude outside [-180, 180] — validation error returned
- Latitude outside [-90, 90] — validation error returned
- Missing required fields lon or lat — schema validation error
- Latitude near ±90° is clamped to ±85.0511° silently rather than erroring
- Network timeout or service unavailability returns a non-2xx HTTP error
