Yes. The core tool and its standard result or export are free to use.
Do I need an account?
No for the core utility. An account or private management token is requested only for capabilities that must persist, such as editable dynamic QR links.
Can I trust the result?
The method and assumptions are visible above. Time-sensitive tools name their sources and freshness; important financial, safety, legal, or operational decisions should be verified with the primary authority.
