Small, documented datasets for researchers, builders, journalists, and anyone who wants to verify the chart instead of screenshotting it.

DATASET 03ON REQUEST · 24-HOUR CACHE

Domain public record

Registration, DNS, HTTPS, mail, and technical-completeness signals for one valid domain, with an optional retained change ledger.

  • Replace example.org in the endpoint with a complete domain
  • Add ?include=history for retained changed snapshots
  • No private WHOIS, inferred owner, traffic, price, or legitimacy claim

DATA CONTRACT

Useful because the caveats travel with it.

Stable fields

Every endpoint declares a schema version. Fields may be added; existing fields will not be silently redefined within a schema version.

Source fidelity

DomainSense normalizes primary records but does not convert registration counts into claims about people, organizations, traffic, usage, or value.

Availability

The service is public and cacheable, but it is not sold as a guaranteed infrastructure dependency. Keep the source links and cache responsibly.
