Use when checking what changed at a place between two dates (construction, deforestation, flooding, crops). Input: lat, lon, radius_m (200-10000), before and after dates (20+ days apart). Output: JSON per date: clearest scene, area cloud %, NDVI mean/median, true color, NDVI and false color PNG URLs; NDVI change and reliability. No scene: 404, not charged. Example: ?lat=37.5665&lon=126.978&before=2026-04-15&after=2026-10-08
