One-call unified passive report: subdomains + DNS summary + SSL summary + archive first/last-seen + threat blocklist flags, each section degrading independently
Working example
Parameters
The registrable domain to enrich (a bare host like example.com; a full URL or leading www. is accepted and normalized). NOT a person.
Which passive sources to query (comma-separated string or array). Defaults to all five. Unknown names are ignored.
If true, reveal the RDAP abuse mailbox / contact email. Default false → contact emails are masked (R17 privacy hygiene).
