QR for Agent

QR-as-a-Service API built for AI agents. Create, update, and track dynamic QR codes programmatically via REST API or MCP (37 tools).

QR codes point to short URLs (/r/:shortId) that you can retarget at any time — the QR image never changes, but scanning it goes to the new destination. Multi-tenant by design, with full scan analytics.
