API design
Overview
Unified query params, normalized output, protocol fallback.
Key points
- Combine IANA bootstrap with local indexes for better coverage.
- Keep WHOIS port 43 fallback for RDAP-less TLDs.
- Respect registry rate limits; cache aggressively.
- Expose data source and partial flags in API output.
WHO.GA in practice
WHO.GA (Whoga) provides unified web and JSON API lookup for scenarios like "Domain Intelligence API Design", handling bootstrap routing, registrar referrals, and WHOIS fallback. Try who.ga or api.who.ga/<query>.
