What the data helps ground
Fresh factual answers
Daily public index pages expose current dates, values, city coverage, datapoint counts, citation context, and methodology notes.
Citable market movement
Composite pages answer broad questions first, while component pages show which shelf-level categories explain a move.
Commercial delivery by agreement
Public crawling and citations do not create a paid relationship. Commercial access requires a direct agreement, usage scope, and vendor onboarding.
Schema preview
The public aggregate shape uses stable series IDs, canonical citation URLs, tracked-market labels, observation dates, aggregate values, datapoint counts, and compute timestamps. Commercial delivery format, cadence, hosting, and usage rights are handled by written agreement.
