datadeltas — monitors, not snapshots

Most scrapers answer "what's there right now?" Every actor here answers the more valuable question: "what changed since you last looked?"

Each actor keeps state between runs and emits only new or changed records — so you schedule it, pay per change detected, and pipe the output straight into Slack, a webhook, a sheet, or your own pipeline. No diffing on your side, no duplicate rows, no re-paying for data you already have.

What you'll find here:

  • 🏛️ Compliance & registers — sanctions-list deltas, enforcement actions, product recalls, lobbying-register changes
  • 📈 Markets & filings — SEC 8-K item alerts, IPO/S-1 filings, 13F & N-PORT holdings diffs, crypto exchange listings
  • 📋 Procurement & grants — UK, ANZ, UN/World Bank tenders; grants.gov + EU funding calls
  • 🛒 Price & stock intel — AU/UK grocery, hardware and pharmacy price-drop feeds
  • 🏗️ Lead generation — new business registrations, building permits/consents, WARN layoff notices

House rules on every actor: official or public data sources, documented output schemas that only change with a version bump, honest READMEs (coverage limits and data lag stated up front), and a first run that seeds state without spamming you.

Found a gap in a feed, or want a source added? Open an issue on the actor — schemas are checked weekly.
