HALOWERK Baltic Land – Maximum Surface Slope (Latvia)
x402
HALOWERK Baltic Land – Maximum Surface Slope (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 maximum adjacent-cell surface gradient (steepest slope) across a local analysis grid for a given WGS84 coordinate within Latvia.

How this service works
Maximum adjacent-cell surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Latvia; results outside it are rejected before payment.
Output
A numeric value representing the maximum adjacent-cell surface gradient (steepest slope metric) across the analysis grid centered on the input coordinate. Only coordinates falling within the Natural Earth boundary for Latvia are accepted; out-of-bounds requests are rejected before any charge is incurred.
Example use cases
Construction site terrain assessment
“I'm evaluating a plot in Latvia at latitude 57.23, longitude 25.42 — can you tell me the maximum slope across that area so I can assess if it's suitable for building?”
Landslide risk pre-screening
“We're doing a risk assessment for a site near Sigulda, Latvia — latitude 57.15, longitude 24.87. What's the steepest surface gradient there? We need it to flag any slope-related hazards.”
Agricultural land suitability check
“I'm looking at farmland in Latvia at coordinates 56.72 latitude, 26.34 longitude. Can you give me the maximum slope at that location so I can see if it's too steep for machinery?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/lv-max-slopeWhen to prefer
Use this endpoint when you specifically need the maximum surface gradient (steepest slope) at a precise geographic coordinate within Latvia, particularly for terrain suitability assessments, risk screening, or geospatial data enrichment workflows. Prefer it over general-purpose DEM APIs when you need a pre-validated, Latvia-scoped result with pay-per-call pricing and no subscription overhead.
Side effects
- Coordinate outside Latvia boundary — rejected with a geographic validation error before payment
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Missing or malformed latitude/longitude — request rejected with input validation error
- Network or service unavailability — HTTP 5xx response
