How this service works
Does the domain carry a linear domain-verification TXT record? Reads the apex TXT records (Cloudflare DoH) and reports whether the linear ownership token is present and the token value (truncated). A present token usually means the company uses linear's product; absence means not verified there. $0.01 per lookup.
Output
Returns whether the Linear domain-verification TXT token is present at the apex of the queried domain, along with the truncated token value if found, and absence information if not. Sourced via Cloudflare DNS-over-HTTPS.
Example use cases
Prospect SaaS tool research
“I'm researching potential customers for a Linear integration — can you check if stripe.com has a Linear verification TXT record in their DNS?”
Competitor tech stack analysis
“I want to know what project management tools our competitor uses — check if notion.so has a Linear ownership token in their DNS apex records.”
Partnership tech fit check
“Before we reach out, can you verify whether figma.com has a Linear domain verification record so I know if they're already using Linear?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/verification/linear?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to determine whether a specific company/domain is a Linear customer or has claimed their domain in Linear, based solely on DNS TXT record inspection. Prefer this over manual DNS lookups or broader SaaS-detection tools when the specific signal needed is the Linear ownership token. Best for sales intelligence, tech-stack research, or integration compatibility checks.
Side effects
- Domain does not exist or has no TXT records — returns absence/not-found
- Cloudflare DoH unreachable — lookup fails with network/upstream error
- Invalid domain format supplied — bad request error
- Domain has TXT records but no Linear token — returns 'not verified' result
- Rate limiting or payment failure — 402 or quota error
