How this service works
Difference between maximum and minimum sampled surface elevation. The coordinate is validated against the Natural Earth boundary for Hungary; results outside it are rejected before payment.
Output
Returns a numeric value representing the local relief — the difference in meters between the maximum and minimum sampled surface elevations — at the specified coordinate within Hungary. Coordinates outside the Hungarian boundary are rejected before any charge is applied.
Example use cases
Agricultural land suitability assessment
“I'm evaluating farmland near Budapest. Can you get the local terrain relief at latitude 47.45, longitude 18.9 — I need to know how variable the surface elevation is there to assess whether it's suitable for mechanized farming.”
Real estate terrain due diligence
“We're looking at a plot in the Hungarian countryside at lat 46.8, lon 17.5. Can you check the local relief to understand how hilly or flat the land is before we invest?”
Flood risk terrain screening
“For our flood risk model, can you pull the local surface elevation relief at 47.1 latitude and 20.3 longitude in Hungary — we need to know the elevation range to estimate how water might accumulate there.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hu-local-reliefWhen to prefer
Choose this endpoint when you need Hungary-specific local terrain relief data validated against official country boundaries, ensuring you are never charged for out-of-scope coordinates. It is ideal for geospatial workflows, land assessment, or environmental modeling focused on Hungarian territory where surface elevation variability at a point is the key metric.
Side effects
- Coordinate outside Hungary boundary: rejected before payment, returns validation error
- Coordinate outside published European coverage bounds (lat 34–72.5, lon -31.5–40.5): rejected with input validation error
- Network or service unavailability: HTTP 5xx error
- Malformed or missing latitude/longitude fields: HTTP 4xx validation error
- Payment failure via x402 protocol: transaction not processed, no result returned
