I build data tools on Apify. The rule I stick to: only official, publicly documented endpoints. No login walls, and no scraping that fights the website. It keeps the data clean, the legal side simple, and the Actors stable, since an official API doesn't break when someone redesigns their frontend.

Results come back in one consistent schema with stable IDs, so you can diff two runs and see what appeared or disappeared since last time. That makes these Actors useful for monitoring, not just one-off exports.

Job Postings API  pulls live job postings from company career boards running Greenhouse, Lever, Ashby, Workable or SmartRecruiters. You give it a list of companies, it works out which ATS each one uses and returns every open role in the same JSON format, with filters for keywords, location and remote. Monitor mode reports only new and closed roles, so you can get hiring alerts on a schedule.

Government Tenders API  searches and monitors public procurement from SAM.gov (US federal), TED (EU) and UK Find a Tender in one schema: keywords, CPV and NAICS codes, countries, deadlines and estimated values. Monitor mode reports only new tenders.

Bluesky Scraper  collects posts with engagement counts, keyword post search, profiles, followers and full reply threads through the official AT Protocol API.

If something breaks or you need a field the Actor doesn't return, open an issue on the Actor page. I check most days and usually reply within a day or two.
