Your AI finally gets French real estate right.

IRL rent reviews, service-charge reconciliation, compliant rent receipts: exact regulatory calculations (Law 89-462, Decree 87-713), served by the API of the synergieloc property-management software. And for buildings: plans, DXF, IFC and 4K tours from a JSON scene, checked against the building code of the country you declare. Plug in your AI agent, pay as you go.

3D CAD — production is free until 2026-12-31 inclusive (98 day(s) left). After that, producing a DXF, an IFC model, a PDF sheet, a camera plan or a 4K tour will cost 2 units per call. Checks stay free and keyless, permanently (geometric audit, weathertightness, documentation completeness, building codes, schema, catalogues) — a check you hesitate to call never gets called. Your free calls are already metered: GET /api/v1/usage tells you today what you would have paid. Machine-readable: GET /api/v1/tarifs · full price list: /tarifs (in French).
