HALOWERK Baltic Land – Mean Surface Slope (Latvia)
x402
HALOWERK Baltic Land – Mean 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 mean first-order surface gradient (slope) across an analysis grid cell for a given WGS84 coordinate within Latvia.

How this service works
Mean first-order 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 mean first-order surface gradient (slope) computed across the analysis grid cell containing the specified coordinate. Coordinates outside Latvia's Natural Earth boundary are rejected before any payment is charged.
Example use cases
Construction site terrain assessment
“I'm evaluating a potential construction site near Riga at latitude 56.92, longitude 24.08 — can you get me the mean surface slope there so I know how steep the terrain is?”
Agricultural land suitability screening
“I need to check the average slope of farmland at coordinates 57.15 north, 25.30 east in Latvia — is it flat enough for mechanized farming?”
Flood risk and drainage planning
“For a drainage engineering project at latitude 56.65, longitude 23.72 in Latvia, what's the mean first-order surface gradient at that point?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/lv-mean-slopeWhen to prefer
Choose this endpoint when you need the mean terrain slope (first-order surface gradient) for a specific point in Latvia, especially for geospatial analysis, land suitability assessment, drainage modeling, or environmental studies. It is tightly scoped to Latvia (Natural Earth boundary validated) and charges only $0.003 USDC per call, making it cost-effective for batch coordinate lookups. Prefer sibling endpoints on the same host for maximum slope, ruggedness, or other terrain/soil attributes.
Side effects
- Coordinate outside Latvia boundary — request rejected with a validation error before payment
- Coordinate within European coverage range but outside Latvia — rejected by boundary check
- Missing or malformed latitude/longitude fields — request returns a schema validation error
- Coordinate at an extreme or edge of the Latvian boundary — may return null or edge-case value
- Network timeout or service unavailability — request fails without charge
