# HALOWERK Atlantic Land – Ireland Solar Orientation Index

> HALOWERK Atlantic Land – Ireland Solar Orientation Index is a paid API for AI agents from atlantikland.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 aspect and slope) for a given coordinate within Ireland, validated against Ireland's Natural Earth boundary.

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-atlantic-land-ireland-solar-orientation-index-6709b8ab -d '<json body>'
```

Example prompt: What's the south-facing slope orientation index for the location at latitude 52.1 and longitude -8.5 in Ireland — I want to know how suitable the terrain is for solar exposure.

## When to prefer this

Use this endpoint when you need a terrain-derived solar orientation score specifically for a location within Ireland, grounded in aspect and slope data. Prefer it over generic elevation or slope APIs when the use case is solar suitability, south-facing land assessment, or renewable energy site screening in an Irish context. It includes built-in boundary validation so out-of-scope coordinates are caught cleanly.

## Known failure modes

- Coordinate outside Ireland's Natural Earth boundary — request rejected with validation error before payment
- Latitude or longitude out of published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Malformed or missing coordinate fields — request returns input validation error
- Service unavailable or timeout — no result returned

## How this service works

South-facing slope orientation index derived from aspect and slope. The coordinate is validated against the Natural Earth boundary for Ireland; results outside it are rejected before payment.

## Output

A numeric south-facing slope orientation index for the queried Irish coordinate, computed from aspect and slope data. Coordinates outside Ireland's Natural Earth boundary are rejected before any computation or payment is applied.
