How this service works
Does a website use Vercel? Fetches the page (homepage for a bare domain) and matches Vercel's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (hosting). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.
Output
Returns a yes/no answer indicating whether the website uses Vercel, along with an evidence snippet (HTML content or response header values that matched Vercel fingerprints) and a category label of 'hosting'.
Example use cases
Sales prospecting for Vercel agencies
“I'm building a list of potential clients who are already on Vercel — can you check if acme.com is hosted on Vercel so I know whether to pitch our Vercel optimization services?”
Competitor tech stack research
“I want to know if my main competitor, notion.so, is using Vercel — check their site and show me what evidence you found.”
Pre-migration hosting audit
“Before we migrate our client's site away from their current host, can you confirm whether their site at example.com is currently running on Vercel?”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/uses/vercel?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, low-cost ($0.01) binary check specifically for Vercel hosting detection on a single domain. Prefer it over general tech-stack scanners when your workflow targets Vercel specifically for sales outreach, migration planning, or competitive technographic research. Choose sibling endpoints for other technologies (IIS, Elasticsearch, etc.).
Side effects
- Domain is unreachable or returns a non-200 response, preventing fingerprint matching
- Site uses bot protection or blocks crawlers, returning misleading HTML
- Vercel fingerprints may not be present if the site uses edge caching or custom domains without standard Vercel headers
- False negatives if the site partially uses Vercel but the homepage does not expose fingerprints
- Missing or malformed query parameter causes a 400 error
