Research Workflow

Step 1: Check Availability

# Quick WHOIS check
curl -s "https://mcp.domaindetails.com/lookup/{domain}" | jq '.available // .registrar'

Step 2: Check Marketplace Listings

curl -s "https://api.domaindetails.com/api/marketplace/search?domain={domain}" | jq

Step 3: Check Domain History

Use WebFetch to check: - web.archive.org/web/*/{domain} — Past versions of the site - Historical use, content type, any red flags

Step 4: Check SEO Metrics (if SemRush available)

# Domain overview
curl -s "https://api.semrush.com/?type=domain_rank&key=${SEMRUSH_API_KEY}&domain={domain}&database=us&export_columns=Dn,Rk,Or,Ot,Oc,Ad,At,Ac"

# Backlinks overview
curl -s "https://api.semrush.com/?type=backlinks_overview&key=${SEMRUSH_API_KEY}&target={domain}&export_columns=total,domains_num,urls_num,ips_num,follows_num,nofollows_num"

Step 5: Generate Alternatives

If the desired domain is taken, suggest alternatives:

Patterns: - get{brand}.com — getnotion.com - {brand}hq.com — slackhq.com - try{brand}.com — tryfigma.com - use{brand}.com — usefathom.com - {brand}app.com — todoistapp.com - {brand}.io — linear.io - {brand}.ai — jasper.ai - {brand}.co — buffer.co - hey{brand}.com — heysummit.com

## Recommendation
{Buy/Pass/Negotiate — with reasoning}

Important Notes

• WHOIS data is increasingly privacy-protected. Limited registrant info is normal.
• Domain marketplace prices are often negotiable. Listed price is usually the starting point.
• Always check domain history on the Wayback Machine before purchasing. Spam/adult history can carry Google penalties.
• Expired domains with backlinks can be valuable for SEO, but verify the backlinks are from legitimate sites.
• .com is still king for brand trust, but .io (tech), .ai (AI), and .co (startups) are increasingly accepted.
