{"name":"satellite-change","description":"Renders before/after satellite images of the same area for change detection. Produces two cloud-free Sentinel-2 composites of the same bounding box anchored at two dates, each averaged over the window_days prior, and returns both base64 PNGs side-by-side so clients can display, animate, or pixel-diff them. Use cases: construction-site progress, vegetation change, wildfire burn scars, port/parking-lot activity, glacier retreat. Native 10m; bbox area up to 4 sq-deg. Use it as a Sentinel-2 time-series diff, construction monitoring feed, deforestation tracker, or fire-burn-scar imagery source.","price":"$0.05","method":"POST","input_schema":{"properties":{"bbox":{"type":"array","description":"[west, south, east, north] in WGS84 lon/lat. west<east, south<north, area ≤ 4 sq-deg."},"date_a":{"type":"string","description":"Anchor date for the BEFORE composite, YYYY-MM-DD.
