French Property Sale by Identifier: Date, Value, Parcels and Premises (Cerema DVF+)
ceremadvf/mutation-record
The full record of one French property sale (mutation) by its numeric identifier: date, nature (such as Vente), declared value, whether it is a sale of a property still to be built, the communes, sections and parcels involved, counts of premises, houses and apartments by number of rooms, and the built area of each. Take the identifier from a commune's list of sales. Amounts and areas are decimal strings. Source: Ministères économiques et financiers (DGFiP), Demandes de valeurs foncières (DVF), Licence Ouverte 2.0, as enriched by Cerema DVF+; served by Eden Engine; not an official Cerema product. This runs on Cerema's pre-production DVF+ service (the production host has no DNS record), so it may be unavailable or slow; an outage arrives as a retryable error. Geographic and sale-identifier queries only: there is no lookup by a person's name.
