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.
Solid free tier for anyone needing quick data lookups without jumping through billing hoops. The sanctions screener stood out, surprisingly useful for basic compliance checks at 100 requests a month.
Love that the WHOIS endpoint uses RDAP instead of scraping, and the sanctions list actually feels current. Hit a few free-tier requests and response times were snappy, going to bookmark this for weekend projects.
the sanctions screener is genuinely useful, checked a few names against OFAC and it matched up. nice to see this stuff available without locking everything behind a paid plan.
Tested the WHOIS and email validator endpoints on a few domains and both returned fast, clean JSON without me needing to read any docs. Genuinely useful for small side projects.
Tested the WHOIS and IP geolocation endpoints and both returned clean JSON fast, no rate limit headaches on the free tier. Genuinely impressed something this useful ships open source without a credit card wall.
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.
