How this service works
Does the domain carry a slack domain-verification TXT record? Reads the apex TXT records (Cloudflare DoH) and reports whether the slack ownership token is present and the token value (truncated). A present token usually means the company uses slack's product; absence means not verified there. $0.01 per lookup.
Output
Returns whether the apex TXT records of the queried domain contain a Slack domain-verification token, along with the truncated token value if present, and the DNS response code from Cloudflare DoH.
Example use cases
SaaS stack discovery for a prospect
“I'm doing research on hubspot.com before a sales call — can you check if they have a Slack domain-verification token in their DNS records so I know if they're a Slack shop?”
Competitive intelligence on tooling
“I want to know if notion.so uses Slack — can you look up whether their domain has a Slack ownership TXT record?”
Due diligence on acquisition target
“We're evaluating linear.app as an acquisition target — can you check their DNS for a Slack domain verification token to see if Slack is part of their infrastructure?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/verification/slack?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly determine if a specific company or domain has verified ownership with Slack, without scraping their website or querying Slack's API directly. It is ideal for OSINT, sales intelligence, due diligence, or SaaS stack discovery workflows where DNS-based signals are sufficient.
Side effects
- Domain does not exist — NXDOMAIN response with no TXT records
- Domain has no TXT records at all — returns absence of Slack token
- DNS query timeout or Cloudflare DoH unavailability
- Malformed domain input causing query failure
- Token present but truncated value may not reflect full token
