HALOWERK Atlantic Land – Netherlands Local Relief (Elevation Range)
x402
HALOWERK Atlantic Land – Netherlands Local Relief (Elevation Range) is a paid API for AI agents from atlantikland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns the local relief index (difference between maximum and minimum sampled surface elevation) for a given WGS84 coordinate within the Netherlands.

How this service works
Difference between maximum and minimum sampled surface elevation. The coordinate is validated against the Natural Earth boundary for Netherlands; results outside it are rejected before payment.
Output
A numeric value representing the local relief in metres — the difference between the maximum and minimum sampled surface elevation across the analysis grid centred on the submitted coordinate. The coordinate must fall within the Netherlands boundary; requests outside that boundary are rejected before payment is processed.
Example use cases
Flood risk terrain assessment
“I'm evaluating flood risk for a site in the Netherlands at 51.92 latitude and 4.48 longitude — can you tell me the local elevation relief there so I know how much the terrain varies?”
Construction site terrain suitability
“We're planning to build at coordinates 52.09 latitude, 5.12 longitude in the Netherlands — what's the local relief, meaning the elevation range across that area?”
Cycling route terrain profiling
“I want to understand how flat or hilly the terrain is near latitude 53.20 and longitude 6.57 in the Netherlands — what's the difference between the highest and lowest surface elevation there?”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/nl-local-reliefWhen to prefer
Choose this endpoint when you need the local relief (elevation range) specifically for a point within the Netherlands. It is purpose-built for Dutch coordinates with pre-payment boundary validation, making it cost-efficient — invalid coordinates are rejected before the fee is charged. Prefer this over generic elevation APIs when you need the max-minus-min relief metric rather than a single elevation value, and when your workflow targets the Netherlands specifically.
Side effects
- Coordinate outside Netherlands boundary — request rejected before payment, returns validation error
- Coordinate within European coverage bounds but outside Netherlands Natural Earth boundary — rejected
- Malformed or out-of-range latitude/longitude values — schema validation error
- Network or service timeout — transient error, retry recommended
- Payment failure via x402 protocol — call not executed
