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-cz-solar-orientation-b18d3905 -d '<json body>'
```

Example prompt: What's the south-facing slope orientation index for coordinates 49.8175° latitude and 15.4730° longitude in Czechia? I want to assess the solar orientation of that land parcel.

## When to prefer this

Use this endpoint when you need a precise, pre-validated south-facing slope orientation metric specifically for coordinates within Czechia. It is ideal for solar potential screening, agricultural site evaluation, and land suitability workflows where boundary validation against Czechia is required before computation. Prefer it over generic DEM or terrain APIs when you need a single orientation index optimized for solar analysis in Central Europe.

## Known failure modes

- Coordinate outside Czechia Natural Earth boundary returns rejection error with no charge
- Latitude or longitude outside European coverage range (lat 34-72.5, lon -31.5 to 40.5) triggers validation error
- Malformed or missing coordinate fields return schema validation error
- Network or service timeout may occur for high-demand periods

## How this service works

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

## Output

A numeric south-facing slope orientation index derived from terrain aspect and slope data, indicating how strongly the given coordinate faces south. Coordinates outside the Czechia boundary are rejected before any charge is applied.
