Output

Example use cases

“I'm buying a plot of land in Paris and I need to verify the cadastral section and exact surface area in m² for parcel 75101000AI0002 — can you pull that from the cadastre?”
Land area verification for planning
“We're filing a building permit and need to confirm the official contenance in square meters for cadastral parcel 13055000BH0045 in France — can you fetch that?”
Real estate data enrichment
“I have a list of French parcels and I need to enrich each one with its official cadastral section and area — start with parcel 69123000AB0123 and tell me what the cadastre returns.”
