# HALOWERK Atlantic Land – France Soil Texture Classification

> HALOWERK Atlantic Land – France Soil Texture Classification is a paid API for AI agents from atlantikland.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. clay, sandy loam, silt) for a given coordinate in France, 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-atlantic-land-france-soil-texture-classification-70ea1744 -d '<json body>'
```

Example prompt: What's the USDA soil texture class at latitude 44.8, longitude 2.3 in France — is it more sandy, silty, or clay-dominant?

## When to prefer this

Choose this endpoint when you need a standardized USDA soil texture class derived from globally consistent SoilGrids data specifically for a French coordinate. It is ideal for land due-diligence, agricultural planning, or environmental surveys in France where soil composition is a key variable. Prefer this over generic soil APIs when you need France-validated, SoilGrids-backed texture classification at low cost per query.

## Known failure modes

- Coordinate outside France boundary returns a rejection error before any computation
- Latitude or longitude out of published European coverage range (lat 34–72.5, lon -31.5–40.5) returns validation error
- Missing latitude or longitude fields returns a 400-level bad request error
- Network or upstream SoilGrids data unavailability may result in a 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 France; results outside it are rejected before payment.

## Output

A USDA soil texture classification (e.g. sandy loam, clay, silt loam) derived from SoilGrids sand, silt, and clay percentage fractions for the queried coordinate inside France. Coordinates outside France's Natural Earth boundary are rejected before processing.
