Public data
Foncier
Geocoding, cadastre, buildings, risk and solar potential for any French address.
What it does
- Geocode an address and read its cadastral parcel and built footprint
- Check classified-installation (ICPE) risk for a site
- Read comparable sale prices (DVF) and solar productibility by location
Where the data comes from
Open data: no credential to issue, hold or revoke. It reads the same source a person could look up by hand, at a scale nobody has time to do by hand.
Why through Tulina
Most systems now publish their own way for a model to reach them, and that is a good thing — it is what Tulina connects to. The connection was never the hard part. Deciding who may use it, what it is allowed to return, and what the model knows before it asks: that is.
The keys stay in one place
Connect Foncier once. The credential is encrypted in a vault, never held in clear, and never pasted into a chat or a workflow file. A person uses their own key where they have one, their team's where they do not, the organisation's after that — so nobody is blocked and nobody is handed more access than they need. Revoke it once and everything running on it stops.
What leaves is filtered before it leaves
Roles decide who can reach Foncier at all. Beyond that, a policy on the connector itself decides what comes back: fields dropped, identifiers masked or hashed, people pseudonymised. The data is minimised at the source rather than after it has already reached a model.
Every call is on the record
Runs are logged for the organisation — what was called, by whom, when. That is what makes an automated action reviewable after the fact, and what a security review asks for first.
The run starts knowing your company
A direct connection gives a model access. It does not tell it how your company names things, which accounts matter, or what was decided last quarter. Tulina carries that across every tool, so the same request against Foncier returns something usable instead of something generic.
