NAV Navbar


Jatsby is a real estate data API for Florida with grouping of addresses as a core feature. This means that data can be viewed at various geographical areas, from blocks to zip codes and everything in-between.

The API offers information about homes (such as number of bedrooms and last sale price) as well as incidents (crime data, utility outage data, etc.) as that data becomes available from local government.

Absolutely NO data is sourced from an MLS, NAR or any other real estate entity, so Jatsby is not bound by usage limitations or restrictions :D

Groups refer to geographical areas which contain addresses and incidents. The groups are (from smallest to largest):


A collection of addresses, expressed as 3500 Nightscape Circle 32224 (zip code is required)


A small area of usually around 200 homes built at the same time by the same developer. Includes gated communities.


A larger area consisting of multiple subdivisions and businesses.

Zip Code

Get Incidents
