How this service works
TXT record of sftp.<domain>: looks up the sftp 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 sftp without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the TXT record for sftp.<domain> exists, the record values (strings), the TTL in seconds, and the DNS response code — giving a quick signal of whether an SFTP subdomain is DNS-configured without a full subdomain enumeration.
Example use cases
Verify SFTP server DNS setup
“Before we onboard this vendor, can you check if sftp.vendorcorp.com has any TXT DNS records set up — I want to confirm the sftp subdomain actually exists and is configured?”
Security audit of domain SFTP exposure
“I'm auditing company.io's DNS footprint — can you look up whether sftp.company.io has TXT records and tell me what they contain?”
Automate SFTP host discovery
“For each of these client domains, can you check if sftp.<domain> has a TXT record in DNS so I know which ones have an SFTP host configured?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/sftp/txt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, targeted existence check for an sftp subdomain's TXT records on a specific domain, without doing broad subdomain enumeration. Prefer it over generic DNS lookup tools when you specifically need TXT record data on the sftp host and want to use Cloudflare's DoH resolver. It is ideal for infrastructure audits, vendor onboarding checks, and security reconnaissance workflows.
Side effects
- Domain does not exist — NXDOMAIN response with no records returned
- sftp subdomain has no TXT record — empty record set with NOERROR
- Malformed domain input causes query failure
- Cloudflare DoH service temporarily unavailable — upstream DNS error
- Rate limiting or payment failure results in 402 response
