Example use cases
Hiking route elevation profiling
“Can you look up the elevation at latitude 47.8651 and longitude -121.4429? I'm planning a hiking route and need to know how high above sea level that trailhead is.”
Drone flight clearance check
“What is the ground elevation at latitude 33.9425 and longitude -118.4081? I need the terrain height there to calculate safe drone flight altitude.”
Flood risk assessment for a property
“Look up the elevation at latitude 29.9511 and longitude -90.0715 for me — I want to know how high above sea level that location is to assess flood risk.”

Endpoint
GEThttps://workspace-x402-paywall.onrender.com/geo/elevation?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.005 USDC) pay-per-call elevation lookup for a specific lat/lon without committing to a subscription-based mapping API. Ideal for agents doing one-off or low-volume geospatial enrichment, drone path planning, or terrain analysis where a micropayment model via x402 on Base or Solana is acceptable.
Side effects
- Missing lat or lon parameter returns a 400 error
- Invalid or out-of-range coordinate values may return an error or null elevation
- Payment not provided or insufficient USDC results in a 402 Payment Required response
- Coordinates over ocean or unmapped terrain may return zero or null elevation
- Service unavailable on render.com cold-start may cause timeout
