# 4PHILLY.NET — one unified Philadelphia property record
Type any address or OPA number. Get business licenses, open violations, violation history, and 311 complaints — pulled live from the city's own data.
**The trick:** every data point is pulled from *both* Eclipse (the authoritative L&I backend behind li.phila.gov) *and* Carto (the historical mirror at phl.carto.com). When they disagree, 4PHILLY flags it. Eclipse always wins.
This matters because the two drift. License expirations, status changes, and new complaints appear in Eclipse before — sometimes long before — Carto catches up. A landlord can be operating on an expired license while the public open-data feed still shows **Active**. 4PHILLY catches that.

It’s a work in progress.
The repo is here… any issues… let me know.
Version 1.0 is almost ready.
But for now, it works well.
