Expired Domain Screener — Availability, History & Trademark Risk

Screen expired domain lists before you buy — in one run, for every domain you paste in:

• ✅ Live availability from the registry itself (RDAP — the authoritative source, not a cached WHOIS): available, registered, or in the drop cycle (pendingDelete = drops in days, redemptionPeriod = ~30 days).
• 🕰️ Website history from the Wayback Machine: first year seen, last year seen, years archived — spot aged domains with real history vs. fresh names.
• ⚖️ Trademark-risk signals most tools skip: exact famous-mark matches, marks hidden inside the name (google-cloud-support), leetspeak (g00gle) and one-letter typosquats (spotifi). 95% of UDRP disputes against famous marks are lost by the domain holder — filter these out before wasting money.
• ⭐ Brandability score (0-100): length, pronounceability, real dictionary words, hyphen/digit penalties, TLD strength.
• 🏁 One clear verdict per domain: STRONG_PICK, AVAILABLE, WATCH_DROP, AVOID_TRADEMARK, TAKEN, CHECK_MANUALLY.

Plus a second mode for brand owners:

• 🚨 New-registration brand watch (nrdWatch): scans yesterday's newly registered domains (full daily zone feed) for your brand keywords and flags likely phishing/squatting registrations — with registrar and trademark-risk notes. Run it on a daily schedule and get alerts the morning after someone registers your-brand-login.com.

Who uses this

• Domain investors / flippers: filter auction and drop lists down to clean, brandable, UDRP-safe picks.
• SEO agencies: find aged domains with long archive history for authority projects.
• Brand protection / in-house legal: daily watch on new registrations that touch your marks.
• Startups: sanity-check a naming shortlist (availability + trademark landmines) in seconds.

Input example (screen mode)

{
    "mode": "screen",
    "domains": ["greenleafbakerystudio.com", "spotifi.com", "google-cloud-support.net"],
    "includeHistory": true
}

Output example

{
    "domain": "spotifi.com",
    "verdict": "AVOID_TRADEMARK",
    "availability": "AVAILABLE",
    "trademarkRisk": "REVIEW",
    "trademarkNote": "one edit away from famous mark \"spotify\" (typosquat signal)",
    "brandabilityScore": 68,
    "historyFirstYear": 2011,
    "historyYearsArchived": 7,
    "reasons": "Trademark caution: one edit away from famous mark \"spotify\" (typosquat signal). | Strong brandable (68/100). | Web history since 2011 (7+ snapshots, last seen 2019)."
}

Why this one (honest comparison)

Most "expired domain" actors scrape a single third-party website (fragile, breaks often — check their reviews). This screener talks to the authoritative public sources directly (registry RDAP, Wayback Machine CDX, daily zone-file feed) — no login, no API keys, no scraping war — and adds the trademark pre-check nobody else does.

Notes & fair use

• Results are screening signals, not legal advice. Before paying real money for a domain, confirm trademarks with a professional search (USPTO/EUIPO/WIPO).
• Default input runs a demo list that shows every verdict type in ~30 seconds.
• Pay per result — you only pay for domains actually screened (failed lookups are marked and still count as screened results; zero matches in watch mode = zero result charges).
