• limit defaults to 100 and is capped at 500.
• An unknown slug answers 404 not_found — the same answer whether it never existed or belongs to someone else.
• qr.svg returns image/svg+xml with Cache-Control: public, max-age=3600 — embed it directly.

The redirect itself is https://api.fictura.co/l/<slug> — that's the URL you put on the poster. Clicks, installs and re-engagements attribute to the link and surface on the Attribution page and in CSV exports.
