HALOWERK Eastern Land – Hungary Depression Depth
x402
HALOWERK Eastern Land – Hungary Depression Depth is a paid API for AI agents from ostland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns the positive elevation difference between a neighborhood mean elevation and the center cell elevation, indicating topographic depression depth at a given coordinate in Hungary.

How this service works
Positive difference between the neighborhood mean and center elevation. The coordinate is validated against the Natural Earth boundary for Hungary; results outside it are rejected before payment.
Output
A numeric value representing the positive difference between the neighborhood mean elevation and the center cell elevation at the specified coordinate, indicating how deep the terrain depression is at that point. Returns an error or rejection if the coordinate falls outside Hungary's Natural Earth boundary.
Example use cases
Agricultural drainage site assessment
“I'm evaluating a field in Hungary at 46.8° N, 20.1° E for waterlogging risk — can you tell me how deep the terrain depression is at that spot compared to the surrounding area?”
Hydrological flood risk mapping
“For a flood risk study near Budapest at 47.55° N, 18.95° E, I need to know the depression depth — how much lower is the center elevation compared to its neighborhood mean?”
Geodata enrichment for land valuation
“I need the topographic depression depth at coordinates 47.1° N, 17.9° E in Hungary to assess whether the land is prone to water pooling before we proceed with a purchase.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hu-depression-depthWhen to prefer
Choose this endpoint when you specifically need depression depth (neighborhood mean minus center elevation) for a coordinate within Hungary. It is ideal for hydrological modelling, waterlogging risk assessment, agricultural site evaluation, or geospatial enrichment workflows focused on Hungarian territory. The built-in boundary validation ensures only valid Hungarian coordinates are charged, reducing erroneous spending.
Side effects
- Coordinate outside Hungary boundary — request rejected before payment
- Invalid latitude/longitude values outside the published European coverage range
- Coordinate on boundary edge may produce inconsistent boundary validation results
- Network or service unavailability returning non-200 response
- Payment failure via x402 protocol preventing query execution
