# HALOWERK Baltic Land – Latvia Soil Texture Class

> HALOWERK Baltic Land – Latvia 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, sandy clay) for a WGS84 coordinate in Latvia, 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-latvia-soil-texture-class-246c0d5e -d '<json body>'
```

Example prompt: What USDA soil texture class does SoilGrids assign at latitude 56.87, longitude 24.60 in Latvia? I need to know whether the soil there is sandy loam, clay, or something else.

## When to prefer this

Choose this endpoint when you need a standardised USDA soil texture class specifically for a location within Latvia, backed by SoilGrids-derived sand/silt/clay fractions, with built-in boundary validation. Prefer it over generic global soil APIs when working in the Baltic region and when precise USDA classification (rather than raw fraction percentages) is the required output.

## Known failure modes

- Coordinate outside Latvia's Natural Earth boundary — request rejected with a validation error before payment
- Latitude or longitude outside the published European coverage range — schema validation failure
- SoilGrids data unavailable for the queried cell — upstream data error
- Malformed or missing coordinate fields — HTTP 400 bad request

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

## Output

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