Technical Notes

The Gazette API

REST+RDF linked-data pattern. Corporate insolvency notice codes span 2441-2460. The read API is unauthenticated; auth is write-only (for placing notices).

HMLR Land Registry

Free endpoint at api.landregistry.data.gov.uk. Returns RDF/Turtle by default — the SPARQL endpoint is used for Price Paid Index queries. Covers England and Wales only.

High-Appointment-Count Signal

Directors with 10+ other active appointments are flagged. A director on 40+ companies is a common pattern in nominee director operations and phoenix company structures.
