Build PropTech Products with Real Property Data

Access 3.7 million Indiana parcels, assessments, and sales through a single API. Skip the months of data aggregation and start building.

The Problem

Aggregating data from 92 separate county systems takes months

County websites lack APIs -- scraping is fragile and unreliable

Enterprise data providers require 5-figure annual contracts

Data format inconsistency between CAMA, Gateway, and SDF sources

Search by address, parcel ID, or owner across all 92 counties. One endpoint, one response format, every county.

GET /parcels/search?address=...

Multi-year assessment data with land, improvement, and total values. Detect trends and identify over-assessed properties.

GET /parcels/{id}/assessments

Historical sales transactions with prices, dates, and buyer/seller info. Build comparable market analyses programmatically.

GET /parcels/{id}/sales

Parcel boundary polygons as GeoJSON. Render maps, calculate areas, and perform spatial queries without a separate GIS system.

GET /parcels/{id}?include=geometry
