Property API: UK Property Data API Index

Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).

6 of the 25 named sources that could be read published a usable figure; 19 published none and are recorded as not published, never filled in; 1 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in GBP (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 102 candidate sentence(s) were refused by a reviewer with the reason recorded.

The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): median, minimum and maximum published entry price per month across every UK property-data vendor that publishes one, beside the share that publishes at all versus quote-only, which on the first read is the finding: of the vendors read, the ones selling to developers and agencies (Sprift, Nimbus, Hometrack, TwentyCi, PriceHubble) put no price on the page while the ones selling to investors and developers direct (PropertyData, Homedata, Chimnie, PaTMa, LandTech, PropertyEngine) all do.

Published per vendor with its unit (per month, per lookup, per property, per unit), its free tier, whether a government source covers the same field for nothing, and repriced-since the previous read.

102 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
