How this service works
Mean first-order surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Sweden; results outside it are rejected before payment.
Output
Returns the mean first-order surface gradient (slope value) computed across the analysis grid for the given coordinate. The coordinate is validated against the Natural Earth boundary for Sweden; requests with coordinates outside Sweden are rejected before any charge is applied.
Example use cases
Solar farm site suitability assessment
“I'm evaluating a potential solar farm site in Sweden near latitude 63.82, longitude 20.26 — can you get me the mean surface slope so I know if the terrain is flat enough?”
Agricultural land terracing feasibility
“We're considering agricultural development on a plot in Sweden at coordinates 57.70 latitude, 11.97 longitude. What's the average slope of the terrain there?”
Construction site slope risk evaluation
“Before we break ground on a building project in Sweden at 65.58 latitude, 22.15 longitude, can you pull the mean surface gradient to check if we need special foundation engineering?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/se-mean-slopeWhen to prefer
Choose this endpoint when you need mean terrain slope specifically for locations within Sweden, especially when coordinate validation against Sweden's official boundary is required before processing. Ideal for land-use planning, environmental assessment, construction feasibility, or agricultural analysis in Sweden. The pay-per-call x402 pricing ($0.003 USDC) makes it cost-effective for on-demand point queries.
Side effects
- Coordinates outside Sweden's Natural Earth boundary are rejected with a validation error before payment
- Coordinates outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) are rejected
- Network timeout or service unavailability may result in no response
- Invalid or missing latitude/longitude values return a schema validation error
