Domain Age & Registration Checker (RDAP)
Upload a list of domains and get creation date, expiry date, registrar and status for each through RDAP, the official registration data protocol, then export a CSV.
Economics
- Pricing example
- $10 for 5,000 lookups (free: 100)
- Daily math
- 2 packs a day x $10 = $20/day.
- Target if you hit the daily math
- Target: $550 - $750 / month if the daily math is hit
Audience and urgency
Audience: Agencies qualifying lead lists, domain investors, and trust and safety or fraud analysts checking how new a domain is.
Urgency: Domain age is a quick signal for lead quality and fraud checks, but looking up hundreds of domains one at a time is slow. Older WHOIS tools are inconsistent across registries.
MVP scope
- ✓ Paste or upload up to 5,000 domains
- ✓ RDAP lookups via the IANA bootstrap file, with polite rate limits per server
- ✓ Columns: creation date, expiry date, last changed, registrar, status codes, age in days
- ✓ Clear 'not available' for TLDs without RDAP or with redacted data
- ✓ CSV export and credit packs via Stripe
Omitted features
- - Do NOT scrape WHOIS web pages or registrar sites
- - Do NOT show or store registrant personal data
- - Do NOT ignore RDAP server rate limits

One-shot master prompt
Build a "Bulk Domain Age Checker" using RDAP in React with Tailwind CSS and a serverless worker. Core requirements: 1. Input: paste or CSV upload of domains; normalise (strip scheme, paths, www), dedupe and validate. 2. Resolve the RDAP server per TLD using the IANA bootstrap file (data.iana.org/rdap/dns.json, cached daily); query /domain/<name> with per-server rate limits, retries with backoff and a clear user agent. 3. Parse events (registration, expiration, last changed), registrar name, status codes; compute age in days; never display registrant contact entities. 4. Results table with filters (younger than N days, expiring within N days) and statuses: ok, not found, no RDAP for TLD, rate limited (retry later); CSV export. 5. Magic-link auth; free 100 lookups; Stripe Checkout credit packs ($10 / 5,000), one credit per successful lookup.
