How this service works
Bulk is dns hosted by vercel: up to 20 domains in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.
Output
An ordered array of per-domain results matching the input order, each indicating whether the domain's DNS is hosted by Vercel (same answer as the single-domain endpoint), plus a per-item error field and an overall failure count for the batch.
Example use cases
Portfolio DNS audit for Vercel migration
“I have a list of 18 client domains and I need to know which ones are already using Vercel for DNS — can you run a bulk check and give me the results per domain?”
Competitor infrastructure reconnaissance
“Check these 20 domains from our competitor landscape and tell me which ones are DNS-hosted by Vercel — I want to see each result and any that errored out.”
Pre-deployment domain validation
“Before we go live, verify that all 12 domains in this list are actually being served through Vercel DNS — flag any that aren't and tell me if any checks failed.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/bulk/dns/hosted-by/vercel?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have 2–20 domains to check in a single operation and want to avoid making individual serial requests. It is the right choice for batch enrichment pipelines, domain portfolio audits, or any workflow where you hold a list of domains and need Vercel DNS hosting status with concurrency and ordered results. For a single domain, use the single-endpoint equivalent to avoid batch overhead.
Side effects
- Input list exceeds 20 domains — batch limit exceeded error
- Invalid or malformed domain names cause per-item errors without failing the whole batch
- DNS resolution timeout for specific domains results in per-item error field populated
- Network or upstream DoH resolver failure may increase failure count
- Missing required 'input' query parameter returns a 400-level error
