Change Watcher - Push Events for Web and API Changes

Watches URLs with a CSS/XPath/regex selector or a JSONPath query, filters out timestamps, tokens, counters and other rendering noise, and emits a normalized change event only when the watched block really changed. No change, no event, no charge.

Spanish Judicial Auctions, Enriched (BOE + Catastro)

Crawls the Spanish BOE auction portal and returns each property lot enriched with official cadastral data: floor area, year built, use, coordinates, plus normalised encumbrances, occupancy status and per-square-metre arithmetic. No personal data of debtors or any natural person, by design.
