HALOWERK Baltic Land – Terrain Aspect (Estonia)
x402
HALOWERK Baltic Land – Terrain Aspect (Estonia) 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 circular direction of the dominant surface gradient (aspect), clockwise from north, for a given coordinate within Estonia's boundary.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Estonia; results outside it are rejected before payment.
Output
A numeric value representing the circular direction (in degrees, clockwise from north) of the dominant surface gradient at the queried coordinate. Coordinates outside the Estonian boundary are rejected before any charge is applied.
Example use cases
Solar panel siting on Estonian farmland
“I'm evaluating a farm plot in Estonia at 59.21° N, 26.45° E — can you tell me which direction the slope faces there? I want to know if it's south-facing enough for solar panels.”
Forestry microclimate assessment
“For a reforestation project at coordinates 58.4° latitude, 24.8° longitude in Estonia, what's the terrain aspect — which way does the slope face relative to north?”
Hydrological runoff modeling input
“I'm building a water runoff model and need the slope-facing direction for a point in Estonia at 57.85° N, 27.1° E — what's the surface aspect angle clockwise from north?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/ee-aspectWhen to prefer
Choose this endpoint when you need terrain aspect (slope-facing direction) specifically for locations within Estonia, and want coordinate pre-validation against the official Estonian boundary so you are not charged for out-of-bounds queries. It is part of a broader HALOWERK Baltic Land suite of terrain and soil variables, making it ideal for pipelines that also consume slope, ruggedness, or soil layer data from the same provider.
Side effects
- Coordinate outside Estonia's Natural Earth boundary — request rejected before payment, no charge incurred
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing coordinate fields — schema validation error
- Grid cell with no elevation data — may return null or an error response
