Find companies by outbound signal

GET

/domain-intel/search

Prospecting: companies running cold email, filtered by vendor, mailboxProvider, minDomains and minNew (new domains registered in window: 7d, 30d or 90d).

Sorted by growth in the window (default) or by total. Page with limit (1–500) and cursor.

Counts are vendor-matched outbound domains and are lower bounds: a domain we cannot tie to a known vendor is not counted. Cold email from vendors we do not fingerprint is reported separately in unknownVendor, never inside the main figures.

Cost: Free.

Access: only teams with Domain Intel enabled; other teams get 403.
