# HALOWERK Nordic Land – Sweden Soil Texture Classification

> HALOWERK Nordic Land – Sweden Soil Texture Classification is a paid API for AI agents from nordland.halowerk.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).

Returns the USDA soil texture class (e.g. loam, sandy loam, clay) for a coordinate in Sweden, derived from SoilGrids sand, silt, and clay fractions.

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-nordic-land-sweden-soil-texture-classification-70cdd889 -d '<json body>'
```

Example prompt: What's the USDA soil texture class at latitude 59.33 and longitude 18.07 in Sweden? I need to know whether the surface soil there is sandy loam, clay, or something else.

## When to prefer this

Use this endpoint when you specifically need a USDA-classified soil texture category (not raw fractions) for a point in Sweden, and want a single authoritative result derived from SoilGrids sand, silt, and clay data. Prefer it over raw-fraction endpoints when your downstream application needs a named texture class. It's most useful for agricultural planning, environmental assessment, and geospatial enrichment workflows focused on Swedish land.

## Known failure modes

- Coordinate outside Sweden's Natural Earth boundary — request rejected with a geographic validation error, no charge applied
- Coordinate within European bounding box but outside Sweden — rejected by country-level boundary check
- Missing or malformed latitude/longitude fields — validation error returned
- Coordinate in a valid location but SoilGrids data unavailable — data gap error
- Network or upstream SoilGrids service unavailability — server error response

## 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 Sweden; results outside it are rejected before payment.

## Output

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