Build and deploy a data marketplace where sensor data from across the city, traffic, air quality, and footfall, is licensed to urban planners with automatic payments to data owners. Cerulea Studio assembles it from External Data Oracles, the Royalty Standard, and Royalty Clearing so departments and private operators list feeds and are paid on verified usage.
Turn fragmented, department-owned sensor feeds into one licensed marketplace with automatic owner payment.
01.
List every sensor in one place. Traffic, air-quality, and footfall feeds from different departments and operators are registered together, so planners discover and license them from a single marketplace.
02.
Deliver trusted feeds. External Data Oracles verify each feed's data before it is served, so planners license measurements they can rely on rather than unverified exports.
03.
Pay data owners on use. The Royalty Clearing module settles each licensed access to the owning department or operator, ending manual cross-department billing.
04.
Charge and pay by consumption. The Royalty Standard encodes each feed's access terms, so what a planner pays and an owner earns follows verified usage.
05.
Gate feeds behind licenses. Only a planner with an active license reads a feed, so data owners retain control over who consumes their sensors.
06.
Give owners a clear ledger. Each department or operator sees who licensed their feed and what they earned, replacing opaque interdepartmental arrangements.
Follow a sensor feed from listing through a planner's licensed access to automatic payment of the data owner.

Cerulea decomposes the sensor marketplace into modular contracts. Each layer lists feeds, licenses access, verifies data, and settles owners without any department controlling the billing.
A licensed sensor marketplace is a horizontal capability. Here is how different urban actors put it to work.
List sensor feeds owned by traffic, environment, and transit departments in one marketplace and earn on licensed use, turning siloed data into a shared, revenue-generating asset.
Key Asset Types
License verified traffic, air-quality, and footfall data from across the city through one contract, paying automatically and trusting the measurements behind their plans.
Key Asset Types
Monetize privately owned sensor networks by listing feeds for licensed municipal access, receiving usage-based payment without negotiating bespoke contracts per buyer.
Key Asset Types
Whether you are bridging municipal data platforms or ingesting readings directly from field sensors, Cerulea routes both into one marketplace record.
For city systems on existing data platforms. Feed listings and access events are translated into on-chain marketplace records through the API gateway automatically.

Feed & Settlement Record
Building a city sensor marketplace with a unified feed registry, oracle-verified data, licensing, and automatic owner settlement from scratch requires specialised engineers and careful municipal integration. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects municipal data-platform integration benchmarks. Unifying department feeds, wiring oracle verification, and building licensing with automatic owner settlement for an average city takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your licensing and settlement rules into pre-audited WebAssembly binaries and provisions the marketplace and clearing layer instantly.
