28 production Actors tracking SEC enforcement, sovereign debt auctions, corporate registries, modern slavery compliance, sanctions lists, patent disputes, clinical trials, and public procurement across 6 continents — all on one delta-engine pattern:

• Fingerprint, don't re-scrape. Every record is fingerprinted on every run. Unchanged records are never re-delivered, never billed.
• Pay-Per-Event. $0.0005–$0.05 per genuinely new or changed record. An empty run costs a fraction of a cent.
• Entity resolution, not just text. SEC respondents, Singapore entities, sanctioned vessels — cross-linked to real registry identities (EDGAR CIK, UEN, IMO), not left for you to match.
• Built to survive real breakage. An upstream outage is reported distinctly from a code defect — verified live in production.

• SEC Enforcement & Litigation Release Delta Feed — apify.com/stefano_seggio/sec-enforcement-litigation-delta-feed (from $0.02/event)
• Singapore ACRA Corporate Registry Monitor — apify.com/stefano_seggio/singapore-acra-registry-monitor (from $0.01/event)
