Istanbul Route AI. Silent Gemini agent on Arc

Istanbul Route AI replaces Google-Maps-style crowd-sourced traffic data with live municipal fleet telemetry and settles the cost of that data in sub-cent USDC on Arc, paid by an autonomous agent instead of the user. When a driver taps a destination, a silent Gemini 3 Flash agent looks at three OSRM route alternatives and adaptively calls six real-time data tools: İBB traffic index, IETT bus density, incidents, weather, ISPARK parking, and time-of-day context. Each tool call is a one-hundred-micro-dollar USDC settlement on Arc. A full route query costs the user half a milli-dollar, produces five to seven real on-chain transactions, and reaches final decision in under four seconds. The user signs one EIP-3009 TransferWithAuthorization through Circle Gateway at the start of the session. No MetaMask popups after that, no gas, no crypto jargon. The driver sees an Apple-Wallet-style prepaid card that silently ticks down as the agent works. The municipality runs a companion operator console with four live KPIs, a streaming on-chain payment feed (every row linkable to ArcScan), a zone heatmap blended from İBB + IETT, an agent decision-mix ring, and a margin-proof card contrasting Arc fees with Ethereum L1.
