# HALOWERK Baltic Land – Lithuania Soil Silt Fraction (0–5 cm)

> HALOWERK Baltic Land – Lithuania Soil Silt Fraction (0–5 cm) 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 mean SoilGrids silt fraction for the 0–5 cm soil layer at a given WGS84 coordinate within Lithuania, validated against the Natural Earth boundary.

## 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-silt-fraction-0-5-cm-161e55ed -d '<json body>'
```

Example prompt: What's the mean silt fraction in the 0–5 cm soil layer at latitude 54.687 and longitude 25.279 in Lithuania?

## When to prefer this

Use this endpoint when you need granular, point-level SoilGrids silt fraction data specifically within Lithuania (0–5 cm depth) and want built-in boundary validation to avoid paying for out-of-scope coordinates. Prefer this over generic SoilGrids APIs when you need a pay-per-call micro-service with automatic Lithuanian boundary enforcement and x402 payment integration.

## Known failure modes

- Coordinate outside Lithuania boundary — request rejected, no charge
- Latitude or longitude out of European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing coordinate fields — schema validation error
- SoilGrids data unavailable for the queried location — possible null or error response

## How this service works

Mean SoilGrids silt fraction for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Lithuania; results outside it are rejected before payment.

## Output

Returns the mean silt fraction (as a proportion or percentage) for the 0–5 cm soil layer at the queried coordinate, sourced from SoilGrids. Coordinates outside the Lithuanian boundary as defined by Natural Earth are rejected before any charge is incurred.
