Domain Check & Buy (Vercel)

Check domain availability, pricing, and purchase — all via Vercel.

Quick Reference

# Check availability + pricing for a name across TLDs
domain-check myproject

# Check specific TLDs
domain-check myproject com,io,dev,app,ai

# Buy a domain (interactive — needs pty:true)
npx vercel domains buy mydomain.com

# List your owned domains
npx vercel domains list

# Inspect a domain you own
npx vercel domains inspect mydomain.com

# Add domain to a Vercel project
npx vercel domains add mydomain.com my-project

# Transfer a domain into Vercel
npx vercel domains transfer-in mydomain.com

How It Works

Availability Check (domain-check)

Uses the Vercel Registrar API (/v1/registrar/domains/{domain}/price):

• purchasePrice: null → domain is taken
• purchasePrice: <number> → domain is available at that price

$ domain-check myproject
Checking: myproject
-----------------------------------------------------------
DOMAIN                    STATUS         BUY PRICE    RENEWAL
-----------------------------------------------------------
myproject.com             ❌ Taken       -            $11.25
myproject.io              ✅ Available   $46.00       $46.00
myproject.dev             ✅ Available   $13.00       $13.00
-----------------------------------------------------------
Prices from Vercel Registrar

Buying (npx vercel domains buy)

Interactive command — requires pty: true when calling from exec.

# Example exec call
exec(command: "npx vercel domains buy myproject.dev", pty: true, timeout: 30)

The CLI will show price and ask for confirmation before charging.

API Direct (for scripts)

VERCEL_TOKEN=$(jq -r '.token' ~/.local/share/com.vercel.cli/auth.json)
TEAM=$(jq -r '.currentTeam // empty' ~/.local/share/com.vercel.cli/config.json)
TEAM_PARAM="${TEAM:+?teamId=$TEAM}"

# Check price/availability
curl -s "https://api.vercel.com/v1/registrar/domains/example.com/price${TEAM_PARAM}" \
  -H "Authorization: Bearer $VERCEL_TOKEN"
# Returns: { "years": 1, "purchasePrice": 11.25, "renewalPrice": 11.25, "transferPrice": 11.25 }
# purchasePrice: null = taken, number = available

# Buy via API
curl -s -X POST "https://api.vercel.com/v1/registrar/domains${TEAM_PARAM}" \
  -H "Authorization: Bearer $VERCEL_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name": "example.com"}'

Vercel CLI Domain Commands

Typical TLD Pricing (Vercel)

Auth

Requires Vercel CLI authentication (npx vercel login). Token is read from ~/.local/share/com.vercel.cli/auth.json.

Team ID is auto-detected from Vercel CLI config, or set VERCEL_TEAM_ID env var to override. If neither is set, the personal account is used.

Notes

• Vercel registrar API replaced the old v4 domains/price endpoint (sunsetted Nov 2025)
• domains inspect only works for domains you own — use the price API for availability
• .ai domains are expensive ($140/yr) across all registrars
• When buying via CLI, use pty: true for the interactive confirmation prompt
