What it needs from you
Discovery mode (optional)optional
— auto (default: one name → apex+CT, several names → list), apex (force CT light pull), or hosts (grade only the pasted names). Does not change price_usd.
Focus notes (optional)optional
— Echoed in the report (e.g. “Heroku deprovision Friday”). Does not change price_usd.
Public apex or hostname listrequired
— One public apex (light crt.sh %.domain pull, newest ≤~40 unique hosts) or newline/comma hostnames (≤15 on $1). Scheme/path stripped. No AXFR, no brute wordlists, no OAuth. IP-only/internal hosts are out of scope (SSRF fail closed).
