# HALOWERK Europe Land – Solar Orientation Index (60 m Point)

> HALOWERK Europe Land – Solar Orientation Index (60 m Point) is a paid API for AI agents from euroland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Returns a south-facing slope orientation index derived from terrain aspect and slope for a single coordinate, evaluated over a 60-metre local analysis grid across 30 European countries.

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-europe-land-solar-orientation-index-60-m-point-19ad6a09 -d '<json body>'
```

Example prompt: What's the south-facing slope orientation index for the coordinates 44.6°N, 6.8°E in the French Alps? I want to evaluate the solar potential of that terrain.

## When to prefer this

Choose this endpoint when you need a fast, standardized terrain solar-orientation score for a single point location within Europe and do not need full topographic analysis. It is ideal for site screening, land suitability scoring, or enriching parcel-level datasets with solar aspect data without commissioning a full GIS workflow. Prefer this over generic DEM APIs when you need a pre-computed, consistent index across 30 European countries at a fine 60-metre resolution.

## Known failure modes

- Coordinates outside European coverage bounds (latitude outside 34–72.5°, longitude outside -31.5–40.5°) will return an error
- Missing or malformed latitude/longitude values result in validation errors
- Coordinates falling in ocean or non-land areas may return null or no-data responses
- Flat terrain with near-zero slope may produce a low or undefined orientation index

## How this service works

South-facing slope orientation index derived from aspect and slope. The service evaluates a 60 metre local analysis grid around one coordinate and returns standardized units across all 30 covered countries.

## Output

A standardized south-facing slope orientation index value computed from terrain aspect and slope data over a 60-metre local analysis grid centred on the supplied coordinate, expressed in consistent units applicable across all 30 covered European countries.
