Mercator Forward Projection
x402
Mercator Forward Projection is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).
Converts geographic coordinates (latitude/longitude) to Web Mercator projected coordinates (x/y) in meters

How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object with x (easting in meters), y (northing in meters), and a latitude_clamped boolean indicating whether the latitude was clamped to valid Mercator bounds (approximately ±85.05 degrees).
Example use cases
Map tile coordinate calculation
“I need to project the coordinates for the Eiffel Tower — latitude 48.8584, longitude 2.2945 — to Web Mercator x/y so I can place it on a slippy map.”
Geospatial data pipeline projection
“Can you convert these GPS coordinates — lat 35.6762, lon 139.6503 — to Mercator projected coordinates so I can feed them into my mapping pipeline?”
Distance computation in projected space
“Take the coordinates for Sydney Opera House at latitude -33.8568, longitude 151.2153 and give me the Web Mercator x/y values so I can compute distances in meters on a flat map.”

Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/geometry/mercator-forward?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call Mercator forward projection without running your own math library. Ideal for serverless agent workflows that need to convert a handful of geographic coordinates to projected map space on demand, especially when integrated with x402 micropayment flows.
Side effects
- Latitude out of [-90, 90] range returns validation error
- Longitude out of [-180, 180] range returns validation error
- Missing required lat or lon fields returns 400 bad request
- Extreme polar latitudes (near ±90°) may be clamped, indicated by latitude_clamped=true
