API Portfolio — 5 Free APIs
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.
Hey Product Hunt! 👋
I built this API portfolio using only Cursor IDE — an AI code editor that writes code from plain English. Zero coding experience, but Cursor wrote 100% of the code for all 5 APIs.
Each API wraps free public data sources (RDAP, Wikipedia, DNS, OFAC, UN) into clean, fast JSON. All deployed on Render free tier, listed on RapidAPI for distribution to 4M+ developers.
Free tier: 100 requests/month, no credit card. Would love your feedback — what API should I build next?
