What can an address tell you?
One question about one municipality or county. Answers include sources and caveats. The demo does not remember earlier questions.
Describe what you want to build or investigate. Results distinguish sources callable today, data we hold, data not ingested, and data that needs an agreement.
01 / READING THE DATA
See each answer’s source and status.
Each data section shows its source and status, plus an update time where available. You can distinguish an empty result from an unavailable source or a field that needs an agreement. Registry data describes what is recorded, not a building’s condition.
How to read a response02 / CONNECT
From the demo to your workflow.

The MCP adapter provides address search, lookups, the catalogue and series as tools in compatible clients. It uses the same key and grants as the API; agreement-gated fields still need separate approval.
