## 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-nordic-land-denmark-soil-texture-class-382956ec -d '<json body>'
```

Example prompt: What's the USDA soil texture class at latitude 56.1629, longitude 10.2039 in Denmark — is it sandy loam, clay, or something else?

## When to prefer this

Choose this endpoint when you need a single, authoritative USDA soil texture classification for a specific point in Denmark derived from SoilGrids harmonised global data. It is ideal for per-parcel agricultural analysis, environmental assessments, or data enrichment pipelines targeting Danish land. Prefer it over raw SoilGrids API calls when you want a clean, pre-computed texture class label with Danish-boundary validation built in and a simple pay-per-call pricing model.

## Known failure modes

- Coordinate outside Denmark boundary — request rejected with an out-of-bounds error before payment
- Latitude or longitude outside the declared European coverage range (lat 34–72.5, lon −31.5–40.5) — schema validation error
- SoilGrids data unavailable or missing for the requested pixel — may return null or an error
- Malformed input (missing latitude or longitude fields) — 400-level validation error
- Network or upstream SoilGrids service outage — 5xx error

## How this service works

USDA texture class calculated from SoilGrids sand, silt and clay fractions. The coordinate is validated against the Natural Earth boundary for Denmark; results outside it are rejected before payment.

## Output

A USDA soil texture class label (e.g. 'Sandy loam', 'Clay', 'Silt loam') derived from the SoilGrids sand, silt, and clay fractions for the 0–5 cm surface layer at the requested coordinate within Denmark. Coordinates outside Denmark's Natural Earth boundary are rejected before any charge is applied.
