How this service works
Mean first-order surface gradient across the analysis grid. The service evaluates a circular 250 metre neighborhood around one coordinate and returns standardized units across all 30 covered countries.
Output
A numeric mean slope value representing the average first-order surface gradient across the 250-metre circular buffer around the supplied coordinate, returned in standardized units consistent across all 30 covered European countries.
Example use cases
Solar farm site suitability screening
“Can you check the average slope within 250 metres of latitude 41.3874, longitude 2.1686 in Spain? I need to know if the terrain is flat enough to be viable for a solar installation.”
Agricultural land gradient assessment
“I'm evaluating a farm plot near latitude 52.2297, longitude 21.0122 in Poland — what's the mean surface gradient in a 250-metre buffer around that point? I need it to estimate erosion risk.”
Construction feasibility terrain check
“What is the mean slope around latitude 47.3769, longitude 8.5417 in Switzerland within a 250-metre radius? I'm doing a preliminary feasibility check for a building project and need the terrain steepness.”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-mean-slope-buffer-250mWhen to prefer
Use this endpoint when you need a quick, standardized slope metric for a single point location anywhere across Europe (30 countries) and a 250-metre analysis radius is appropriate for your use case. It is ideal for site-level assessments such as solar suitability, agricultural erosion, construction feasibility, or ecological corridor planning where terrain steepness at a neighbourhood scale matters. Prefer the 60-metre buffer sibling endpoint for finer, more local slope estimates.
Side effects
- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) will result in an error or empty response
- Invalid or non-numeric latitude/longitude values will cause a validation error
- Locations over open water with no terrain data may return null or zero
- Service may return an error if the x402 payment is not completed or USDC balance is insufficient
