nnu.us Help Center
Guides for nnu.us short links, QR codes, routing, analytics, agent-readable content, REST API, MCP, billing, backup, and security.
REST API and MCP
Call create_link, resolve_link, and get_stats from a compatible agent client with review and least privilege.
QR codes and sharing
Attach an appropriate Open Graph image and verify size, framing, and cached preview behavior.
Plans and billing
Start a secure checkout for the intended interval and wait for confirmed subscription state.
Getting started
Learn where links, analytics, live activity, checks, migration, and billing tools live.
Analytics and link health
Review historical link traffic by time, link, source, location, and client context.
Security and support
Separate public short links from the private Clerk-authenticated dashboard and its account authorization.
Link management
Make a short link stop resolving after a deliberate date and verify the expected recipient behavior.
Import, export, and backup
Know the difference between user imports, logical backups, and operator-level D1 recovery before an incident.
Routing and access
Show a destination inside a framed experience only when the target permits embedding and the result is accessible.
Agent-readable content
Use scan results, source references, challenges, and bounded generation as evidence rather than guarantees.
