How this service works
Is the domain's DNS hosted by vercel? Looks up the NS records (Cloudflare DoH) and matches them against vercel's nameserver patterns, returning yes/no, the nameservers and which ones matched. Vendor detection for sales, migration and security work. $0.01 per lookup.
Output
Returns a yes/no verdict on whether the domain's DNS is hosted by Vercel, the full list of NS records retrieved via Cloudflare DoH, and a subset list of which nameservers matched Vercel's known nameserver patterns.
Example use cases
Sales prospecting for Vercel competitors
“I'm building a list of companies to target for our DNS migration product. Can you check if acme.io is currently using Vercel for its DNS hosting?”
Security audit of supply chain vendors
“We're doing a vendor infrastructure audit — can you tell me whether our supplier domain example-supplier.com has its DNS managed by Vercel, and show me the nameservers?”
Pre-migration infrastructure check
“Before we move our client's site, I need to confirm if theirdomain.com is already on Vercel DNS — can you look up the NS records and tell me if they match Vercel's nameserver patterns?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/hosted-by/vercel?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to detect whether a domain's DNS is managed by Vercel (as opposed to general NS record lookup). Ideal for sales prospecting to find Vercel customers, infrastructure audits to map vendor dependencies, or security workflows that need to identify Vercel-hosted assets. Prefer this over generic DNS lookup endpoints when you need a pre-matched, vendor-specific yes/no answer rather than raw NS records.
Side effects
- Domain does not exist or has no NS records — returns no match with empty nameserver list
- Cloudflare DoH lookup fails due to network issues — lookup error returned
- Invalid or malformed domain input — request rejected with validation error
- Domain uses Vercel-adjacent but unrecognized nameserver variants — may return false negative
