Le Vrai Prix
A sovereign rental-listing auditor that flags overpricing and fraud against official French data.
French rental listings are opaque: a renter can’t easily tell whether a price is fair or a listing is even real. The ground-truth data exists. It’s just scattered across separate official sources.
An ADK agent running on Vertex AI / Cloud Run cross-checks any listing against five official data.gouv.fr sources to flag overpricing and fraud signals. “Sovereign” means every judgement is grounded in authoritative French public data, not a general model’s guess.
Built solo at Sovereign Agents 2026 (Paris). An end-to-end agent on Google Cloud calling real government data sources.
Grounding an agent in authoritative public data beats a bigger model guessing. The hard part isn’t the model; it’s having the right official sources to check against.
