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-southern-land-malta-soil-silt-fraction-0-5-cm-78780d70 -d '<json body>'
```

Example prompt: What is the SoilGrids mean silt fraction in the 0-5 cm topsoil layer at latitude 35.9 and longitude 14.4 in Malta?

## When to prefer this

Choose this endpoint when you specifically need the SoilGrids mean silt fraction for the top 0-5 cm layer at a point location in Malta. It is ideal when building soil texture profiles, feeding USDA texture class calculations, or conducting agricultural or environmental land assessments within the Maltese territory. Pair it with the sibling sand, clay, and CEC endpoints from the same provider for a complete soil characterisation.

## Known failure modes

- Coordinate outside Malta boundary — request rejected before payment is processed
- Latitude or longitude outside the declared European coverage range (34–72.5°N, -31.5–40.5°E) — validation error
- Invalid coordinate format or missing required fields — input schema validation failure
- SoilGrids upstream data unavailable — service 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 Malta; results outside it are rejected before payment.

## Output

A numeric mean silt fraction value (as returned by SoilGrids) for the 0-5 cm depth layer at the queried coordinate, representing the proportion of silt particles in the topsoil at that location within Malta.
