# HALOWERK Central Land – Slovenia Local Relief

> HALOWERK Central Land – Slovenia Local Relief is a paid API for AI agents from mitteleuropa.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Returns the local relief (difference between maximum and minimum sampled surface elevation) for a given coordinate within Slovenia

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability halowerk-central-land-slovenia-local-relief-157e0751 -d '<json body>'
```

Example prompt: What's the local relief — the difference between the highest and lowest nearby elevation — at latitude 46.12, longitude 14.48 in Slovenia?

## When to prefer this

Choose this endpoint when you need to quantify local terrain roughness or relief specifically within Slovenia using a per-point API call. It is ideal for applications that need a quick, single-coordinate terrain variability metric without downloading raw DEM tiles. Prefer it over raw elevation lookups when you need relief (max-min spread) rather than absolute elevation, and over general European endpoints when your use case is constrained to Slovenia with its built-in boundary validation.

## Known failure modes

- Coordinate outside Slovenia boundary — rejected before payment with a boundary validation error
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Malformed or missing coordinate fields — input validation error
- Network or service timeout — transient error requiring retry

## How this service works

Difference between maximum and minimum sampled surface elevation. The coordinate is validated against the Natural Earth boundary for Slovenia; results outside it are rejected before payment.

## Output

A numeric value representing the local relief in meters — the difference between the maximum and minimum sampled surface elevations within the analysis neighborhood around the given coordinate. Requests with coordinates outside Slovenia's Natural Earth boundary are rejected before any charge is applied.
