REST design, error models, cache keys, and multi-source merge.
WHOIS API
Overview
REST design, error models, cache keys, and multi-source merge.
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 "WHOIS JSON API Integration Guide", handling bootstrap routing, registrar referrals, and WHOIS fallback. Try who.ga or api.who.ga/<query>.
