How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
A JSON object containing the queried latitude, longitude, and the elevation at that point in meters (e.g. {"latitude": 40.7128, "longitude": -74.006, "elevation_m": 34.31}).
Example use cases
Terrain check for hiking route
“I'm planning a hiking trail and need to know the elevation at 36.4560° N, 116.8660° W — what's the height above sea level there?”
Construction site ground level
“Can you tell me the elevation in meters for the coordinates 51.5074° N, 0.1278° W? We need it for a construction planning document.”
Drone flight altitude planning
“I need the ground elevation at 37.7749° latitude and -122.4194° longitude so I can calculate safe drone flight altitude above that point.”

Endpoint
GEThttps://anibalb.duckdns.org/x402/geo-elevation?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call elevation lookup for a specific lat/lon coordinate without needing to set up an account or API key. Ideal for AI agents performing one-off geospatial enrichment, route planning, or terrain analysis at $0.002 USDC per call via x402 on Base.
Side effects
- Missing or invalid latitude/longitude parameters returns an error
- Coordinates over ocean or extreme poles may return zero or null elevation
- Service unavailability due to underlying DEM data source outage
- Malformed query parameters result in 400-level error
