HALOWERK Baltic Land – Local Relief (Latvia)
x402
HALOWERK Baltic Land – Local Relief (Latvia) is a paid API for AI agents from baltikum.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns the local relief index (max minus min surface elevation) for a WGS84 coordinate within Latvia's boundaries.

How this service works
Difference between maximum and minimum sampled surface elevation. The coordinate is validated against the Natural Earth boundary for Latvia; results outside it are rejected before payment.
Output
A numeric value representing the local relief — the difference in meters between the maximum and minimum sampled surface elevations within the analysis grid centered on the given coordinate. Coordinates outside Latvia's Natural Earth boundary are rejected before any computation or payment.
Example use cases
Site suitability for construction in Latvia
“I'm evaluating a building site near Riga at 56.95° N, 24.11° E — can you tell me the local relief there so I know how flat or hilly the terrain is?”
Agricultural terrain assessment
“I need to assess whether the land around 56.5° N, 27.3° E in Latvia is suitable for large-scale farming — what's the local elevation relief at that point?”
Flood risk terrain screening
“For a flood risk pre-screening, can you get me the local relief index at 56.65° N, 23.72° E in Latvia? I want to know how much elevation variation there is in that area.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/lv-local-reliefWhen to prefer
Choose this endpoint when you need terrain ruggedness or topographic variability specifically for a point location within Latvia. It is ideal for land analysis, site assessments, and geospatial enrichment workflows targeting Latvian coordinates. Prefer this over generic elevation APIs when you need the relief range (max–min) rather than a single elevation value, and when coordinate validation against Latvia's boundary is a desired safety guarantee.
Side effects
- Coordinate outside Latvia's Natural Earth boundary → request rejected before payment, likely 400 or 422 error
- Coordinate within European bounding box but outside Latvia → validation failure
- Latitude or longitude outside the published European coverage range (34–72.5° N, -31.5–40.5° E) → schema validation error
- Network timeout or upstream elevation data unavailable → 503 or timeout error
- Malformed input (non-numeric or missing coordinates) → 400 bad request
