# HALOWERK Baltic Land – Estonia Soil Texture Classifier

> HALOWERK Baltic Land – Estonia Soil Texture Classifier is a paid API for AI agents from baltikum.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. sandy loam, clay) for a given WGS84 coordinate in Estonia, 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-baltic-land-estonia-soil-texture-classifier-96570e08 -d '<json body>'
```

Example prompt: What's the USDA soil texture class at latitude 58.3793, longitude 26.7290 in Estonia? I need to know if it's sandy loam or more clay-heavy for a planting decision.

## When to prefer this

Choose this endpoint when you need a standardized USDA soil texture classification for a specific point in Estonia, derived from the authoritative SoilGrids dataset. It is ideal for agricultural planning, environmental assessments, and land suitability analysis within Estonian territory. Prefer it over generic soil APIs when you specifically need SoilGrids-backed fractions with built-in Estonian boundary validation and per-call micropayment pricing.

## Known failure modes

- Coordinate outside Estonia boundary — request rejected before payment, no charge incurred
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Missing required latitude or longitude parameter — schema validation error
- SoilGrids upstream data unavailable for the queried cell — may return error or null texture class
- Network timeout or service unavailability — standard HTTP 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 Estonia; results outside it are rejected before payment.

## Output

Returns the USDA soil texture class (e.g. 'Sandy Loam', 'Clay Loam', 'Silt') derived from SoilGrids sand, silt, and clay fractions for the queried Estonian coordinate. Coordinates outside Estonia's Natural Earth boundary are rejected before any charge is applied.
