Do I need to know French law to use the API?

No. That’s the point. FairePlace encodes the legal requirements so you don’t have to. The API returns specific 422 errors with legal references when constraints are violated.

What if the law changes?

We update the API with each legislative change. Decree 2024-127 (e-signature), Decree 2024-1205 (mobility lease), and the annual DPE restriction updates are all handled automatically.

Never worry about French rental law compliance again

17 mandatory clauses, 28 rent-control zones, IRL index — all handled by the API.
