How this service works
TXT record of blog.<domain>: looks up the blog host under the domain you give (TXT via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like blog without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the blog.<domain> subdomain exists in DNS, along with any TXT record values and their TTL as answered by Cloudflare DoH, plus the DNS response code (e.g. NOERROR, NXDOMAIN).
Example use cases
Verify blog subdomain before launch
“Before we go live, can you check if blog.mybrand.com is already set up in DNS and what TXT records it has?”
Audit competitor blog presence
“I want to know if blog.competitorsite.com exists and whether it has any TXT records configured — can you look that up?”
Detect SPF or verification TXT on blog host
“Does blog.startupxyz.com have any TXT records in DNS? I need to know if there's an SPF or domain verification entry on that host.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/blog/txt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted check for TXT records specifically on the blog subdomain of a domain, without enumerating all subdomains. Prefer it over generic DNS lookup tools when you want a purpose-built, low-cost check focused solely on the blog host via Cloudflare DoH.
Side effects
- NXDOMAIN returned when blog subdomain does not exist
- No TXT records present even if host exists (returns empty record set)
- Invalid or malformed domain input causes lookup failure
- Rate limiting or DoH upstream timeout from Cloudflare
- Payment not processed, endpoint returns 402
