API keyJSON
Get ATTRIBUTES field group data for a property by UPRN — a structured view of internal configuration, size, tenure and usage, with confidence scores and modelled flags on the key fields.
Purpose
- Comprehensive profiling — understand how a property is laid out, sized and occupied.
- Valuation & context — supply room counts, floor area, tenure and style to pricing and risk models.
- Confidence-aware — many attributes carry a confidence score and a modelled flag so you can weight or filter them.

Many fields include companion keys — FIELD$CONFIDENCE (a confidence indicator) and FIELD$MODELLED (a boolean flagging whether the value was modelled rather than observed). Use them to weight or filter values in automated workflows.
