## 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-coarse-fragment-volume-0-5-cm-d84b0028 -d '<json body>'
```

Example prompt: What's the SoilGrids coarse-fragment volume in the top 0 to 5 cm of soil at latitude 54.6872 and longitude 25.2797 in Lithuania?

## When to prefer this

Choose this endpoint when you need SoilGrids coarse-fragment volume specifically for a point location within Lithuania and want automatic boundary validation to avoid charges for out-of-scope coordinates. It is purpose-built for Lithuanian geospatial analysis, so it is preferable to generic global soil APIs when you are confident the target coordinate is in Lithuania and want low per-call cost ($0.004 USDC).

## Known failure modes

- Coordinate outside Lithuania boundary — request rejected before payment with a geographic validation error
- Coordinate within European coverage bounds but outside Lithuania — boundary check fails
- Missing or malformed latitude/longitude — input validation error
- Latitude or longitude outside published European coverage range (34–72.5 N, -31.5–40.5 E) — schema validation error
- SoilGrids data unavailable for the location (e.g. water body or unmapped area) — null or error response

## How this service works

Mean SoilGrids coarse-fragment volume 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

A numeric value representing the mean volumetric coarse-fragment content (percentage of soil volume occupied by fragments >2 mm) in the 0–5 cm depth layer at the queried coordinate, derived from SoilGrids global soil data. The coordinate is pre-validated against Lithuania's boundary; requests outside Lithuania are rejected before any charge is incurred.
