Reads a crontab and proposes one monitor per scheduled line. Without apply=1 nothing is written; the proposal says what was ignored and why. Passwords in the command are redacted. The body is the crontab itself, as text/plain. Without ?apply=1 nothing is written: you get the proposal — what would become a monitor, what was ignored and why, and what still fits in the free tier. With apply=1 it is all or nothing, under the same rules as POST /api/endpoints. Comments, variables and @reboot are ignored (there is no way to know when to expect a reboot); @daily and friends become the equivalent expression. The command becomes the monitor name, with passwords and tokens redacted first — the name travels in the alert e-mail, in the public dashboard and in the badge.
