x402
HALOWERK Land Compare – Grassland Change 2020–2021 is a paid API for AI agents from landvergleich.halowerk.com, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-15).
Returns the change in grassland land-cover share between ESA WorldCover 2020 (v100) and 2021 (v200) for a 250-metre analysis area at a given European coordinate.

How this service works
Grassland-share change measured from ESA WorldCover 2020 v100 and 2021 v200 for the same 250 metre analysis area. The result is observed map-class change, not a causal claim.
Output
The endpoint returns the grassland land-cover share (as a fraction or percentage) for the queried 250-metre cell in both ESA WorldCover 2020 v100 and 2021 v200, along with the signed difference (delta) between the two years, representing observed map-class change rather than a causal interpretation.
Example use cases
Farmland grassland conversion monitoring
“I need to know whether the area around latitude 47.8, longitude 13.1 in Austria lost any grassland between 2020 and 2021 according to ESA WorldCover — can you pull the signed change figure?”
Environmental due diligence for land acquisition
“Before we finalize this land deal, can you check the grassland share change from 2020 to 2021 at latitude 43.6, longitude 1.4 in southern France so we understand how the land cover has shifted?”
Rewilding progress assessment
“We planted a rewilding corridor near latitude 52.3, longitude 21.0 in Poland — can you tell me if the grassland fraction at that spot actually increased between 2020 and 2021 per ESA WorldCover?”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/worldcover-2020-2021-grassland-changeWhen to prefer
Choose this endpoint when you need a precise, single-point grassland land-cover change figure derived consistently from ESA WorldCover 2020 and 2021 data within Europe. It is ideal for environmental due diligence, agricultural monitoring, rewilding assessment, or any workflow requiring a repeatable, method-consistent grassland delta at a 250-metre resolution. Prefer it over generic GIS queries when you want a pre-computed, API-accessible comparison without setting up your own raster processing pipeline.
Side effects
- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) will be rejected
- Coordinates in ocean or non-mapped areas may return null or zero grassland share
- Payment failure via x402 protocol will block the response
- Ambiguous or missing latitude/longitude values will cause a validation error
