HALOWERK Baltic Land – Estonia Depression Depth
x402
HALOWERK Baltic Land – Estonia Depression Depth 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 positive elevation difference between the neighborhood mean and the center cell elevation (depression depth) for a coordinate within Estonia.

How this service works
Positive difference between the neighborhood mean and center elevation. The coordinate is validated against the Natural Earth boundary for Estonia; results outside it are rejected before payment.
Output
A numeric value representing the positive difference in meters between the mean elevation of neighboring grid cells and the center cell elevation at the requested coordinate. A higher value indicates the center sits deeper in a depression relative to its surroundings. Coordinates outside Estonia's Natural Earth boundary are rejected before any charge is applied.
Example use cases
Flood risk site screening
“I need to know the depression depth at latitude 59.4370, longitude 24.7536 in Estonia — I'm trying to identify if this site sits in a topographic hollow that could be prone to pooling water.”
Agricultural drainage planning
“Can you get me the terrain depression depth for coordinates 57.8500, 27.0200 in Estonia? I'm assessing whether this field needs additional drainage based on how deep the local surface depression is.”
Construction site terrain assessment
“For a building project at latitude 58.9490, longitude 23.5410 in Estonia, what is the positive elevation difference between the surrounding neighborhood mean and the center cell — I need to understand if the site sits in a low point relative to its surroundings.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/ee-depression-depthWhen to prefer
Choose this endpoint when you need a precise, per-point terrain depression depth metric specifically within Estonia. It is ideal for hydrology, flood risk, drainage planning, or site assessment workflows that require knowing how much lower a specific location sits relative to its immediate surroundings. Prefer it over general DEM APIs when you need Estonia-specific boundary validation and a precomputed neighborhood-mean-vs-center elevation difference rather than raw elevation values.
Side effects
- Coordinate outside Estonia boundary — request rejected before payment with an out-of-bounds error
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- No elevation data available for the given coordinate — null or error response
- Malformed JSON body or missing required fields — 400-level error
- Payment not processed correctly via x402 protocol — 402 response
