How this service works
Bulk is dns hosted by cloudflare: 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 results matching the input domain list, where each item contains a boolean indicating whether the domain's DNS is hosted by Cloudflare, a per-item error field if the lookup failed, and an overall failure count for the batch.
Example use cases
Audit vendor domains for Cloudflare DNS
“I have a list of 15 vendor domains I need to onboard — can you check all of them at once and tell me which ones are using Cloudflare for DNS and which aren't?”
Security screening of suspicious domains
“I've flagged these 20 domains as potentially malicious. Can you run them all through a Cloudflare DNS check in one shot and tell me for each one whether it's hosted on Cloudflare, plus highlight any that errored out?”
Migration readiness check for domain portfolio
“We're migrating our DNS infrastructure and I need to know which of our 18 company domains are already on Cloudflare — can you batch check them all and give me a summary of the results?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/bulk/dns/hosted-by/cloudflare?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you have a list of 2–20 domains and want to check Cloudflare DNS hosting status in a single API call rather than making individual requests. It is more cost-efficient and faster than serial single-domain checks when processing multiple domains. Use the single endpoint instead for one-off lookups or when you only have a single domain.
Side effects
- Individual domain lookup fails due to DNS resolution error — surfaced in per-item error field
- More than 20 domains submitted — batch limit exceeded
- Invalid domain format causes per-item failure
- Cloudflare DoH upstream unavailable — results in errors across all items
- Payment not provided or insufficient — 402 response, no results returned
