# Delta Registry

> Pay-per-event regulatory, sanctions, procurement, and corporate-registry monitoring across 28 independently deployed Apify Actors, spanning 12 domains. Delta-classified output — a record unchanged since the last run is never re-delivered and never billed.

Every Actor bills strictly per delivered event: no subscriptions, no seat licenses, no minimum spend. Full pricing, delta-engine methodology, and BYOK disclosure live on the homepage.
