Example response (shape)

{ "data": [ { "county": "Boone", "state": "MO", "sale_date": "…", "item_number": "…", "parcel_number": "…", "location": "…", "legal_description": "…", "acres": …, "winning_bid": …, "taxes_owed": …, "research_fee": …, "overbid": …, "redeem_by": "…", "deed_deadline": "…", "source": "County tax sale results", "source_url": "https://…", "last_updated": "…" } ], "page": 1, "limit": 25, "total": … }

overbid = winning bid minus taxes owed (and minus the county research fee, where the county charges one). In Missouri, interest is paid only on the taxes portion, not the overbid.

redeem_by = last day the owner can pay and redeem. deed_deadline = last day the buyer can get the collector's deed.

acres is null when the county list gives no acreage.

location is null when the county list gives no street address; legal_description is the county's legal description, when given.

research_fee = county research fee included in the winning bid (null if the county charges none).
