x402
HALOWERK Land Compare – Tree Cover 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 2026-09-14).
Returns the change in tree-cover share between ESA WorldCover 2020 and 2021 for a 250-metre analysis area at a given European coordinate.

How this service works
Tree-cover-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
A numeric measure of the signed change in tree-cover share (in percentage points or a comparable unit) between ESA WorldCover 2020 v100 and 2021 v200 for the 250-metre analysis area centred on the supplied coordinate. The result reflects observed map-class differences, not inferred causal change.
Example use cases
Deforestation monitoring at a forestry site
“Can you check how much tree cover changed between 2020 and 2021 at latitude 43.12, longitude 5.93 in southern France? I want to know if the ESA WorldCover data shows a loss in tree coverage for that 250-metre patch.”
Reforestation project progress check
“I'm tracking a reforestation effort in the Black Forest — can you pull the tree cover change from 2020 to 2021 for coordinates 48.32 latitude, 8.07 longitude and tell me if there's a positive shift in tree-cover share?”
Environmental due diligence for land acquisition
“Before we finalise a land purchase in Portugal near latitude 39.55, longitude -8.10, can you check the ESA WorldCover tree cover delta between 2020 and 2021 to see whether tree cover increased or decreased there?”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/worldcover-2020-2021-tree-cover-changeWhen to prefer
Choose this endpoint when you need a precise, single-coordinate tree cover change value derived directly from ESA WorldCover map classes for the 2020–2021 transition period within Europe. It is ideal for environmental monitoring, due diligence, or land assessment workflows that require a documented, satellite-derived signal rather than a modelled or interpolated estimate. Prefer it over generic land-cover APIs when you specifically need the WorldCover 2020 vs 2021 tree-cover dimension rather than built-up area, water, soil, or overall dominant class — all of which are handled by sibling endpoints on the same platform.
Side effects
- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) will return an error
- Missing or null latitude/longitude fields will cause a validation failure
- Payment not included or insufficient (x402 protocol) results in a 402 Payment Required response
- Coordinates on coverage boundaries may produce edge-case artefacts
- Network timeout if the geospatial backend is slow
