5 free dev APIs: WHOIS, Company, Email, Geo, Sanctions

5 production APIs for developers who need data without expensive subscriptions: Domain WHOIS via RDAP, Company Info from Wikipedia + Wikidata, Email Validator with MX + SMTP, IP Geolocation with dual-source fallback, and Sanctions Screener with 20K+ OFAC + UN entities. Built with Cursor AI, no coding skills required. Free tier: 100 requests/month, no credit card. All open source on GitHub.
Adding a webhook option for the sanctions screener would be really useful so we can get notified automatically when new entities are added, instead of having to poll the endpoint.
The dual-source fallback on the IP geolocation API is a really thoughtful touch, especially for anyone who's been burned by flaky single-provider lookups. Love that it's open source too.
Love how each API has its own dual-source fallback logic, especially the geolocation one. Makes the free tier actually reliable instead of just a teaser.
the open source angle is a nice move, makes it easy to trust what the endpoints are actually doing. also love that the free tier needs no credit card, removes that whole friction dance.
