# HALOWERK Baltic Land – Lithuania Soil Texture Class

> HALOWERK Baltic Land – Lithuania Soil Texture Class 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. loam, clay, sandy loam) for a given coordinate in Lithuania, 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-lithuania-soil-texture-class-47d7b980 -d '<json body>'
```

Example prompt: What's the USDA soil texture class at latitude 54.89, longitude 23.90 in Lithuania — is it sandy, loamy, or something else?

## When to prefer this

Use this endpoint when you need authoritative USDA soil texture classification specifically for a point location within Lithuania, derived from the SoilGrids dataset. It is preferable to generic soil APIs when Lithuanian coverage with pre-payment boundary validation is required, ensuring no charges are incurred for out-of-scope coordinates.

## Known failure modes

- Coordinate outside Lithuania boundary — rejected pre-payment with an error indicating the point is outside coverage
- Coordinate within European bounding box but outside Lithuania polygon — validation rejection
- Malformed or missing latitude/longitude — input validation error
- SoilGrids data unavailable for the requested cell — data gap 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 Lithuania; results outside it are rejected before payment.

## Output

Returns the USDA soil texture class label (e.g. loam, sandy loam, silty clay) computed from SoilGrids sand, silt, and clay fractions for the 0–5 cm layer at the given Lithuanian coordinate. Coordinates outside Lithuania's boundary are rejected before any charge is made.
