Upcoming French public-contract EXPIRATIONS — the predictive layer over DECP open data: contracts whose estimated end date falls inside your window (fenetre_mois, 1-24 months), filterable by CPV prefix (cpv=45) and department, with buyer, incumbent holders, lot number, declared subcontracting, and amounts flagged firm price or ENVELOPE (call-offs, subsequent contracts, tranches, framework ceiling). Buyers re-tender 4 to 9 months before expiry: anticipation BEFORE publication. 50 per page.
