Your coordinates, your roof. This hits the live POST /estimate endpoint (real PVGIS solar data, give it a second) with the public demo key. It doubles as live docs: the curl below always mirrors the form.

Set a roof on the left and hit estimate. You'll get annual + monthly yield, full economics (payback, NPV, IRR), CO₂ savings, and the raw JSON.
