# BuyParcelData API

> Nationwide parcel data covering ownership, valuations, zoning, tax records, and more via a simple REST API.

## What is BuyParcelData?

BuyParcelData (BPD) provides parcel data for every county in the United States. The dataset covers **160 million parcels**, representing **100% of US land area** and **100% of the US population**, sourced directly from county assessors, not inferred or aggregated from third parties.

Each parcel record includes 100+ fields: ownership, assessed value, sale history, zoning, tax records, land use, boundaries, and enriched data from external sources including USDA Cropland Data Layer, elevation, and adjacent acreage under the same ownership.

## How it works

1. **Find parcels by geography**: submit a GeoJSON polygon to `POST /parcels/area`. BPD returns the UUIDs of every parcel whose geometry intersects your area.
2. **Fetch records**: pass those UUIDs to `POST /parcels/query` to retrieve full parcel records, or query by any field directly without a geography step.
3. **Point lookup**: use `GET /parcels/point` to find the parcel at a specific lat/lng.
