System And Utility Routes

This page collects the small public utility route groups that are useful to clients and operators.

Routes

• GET /health
• GET /version
• POST /version/negotiate
• GET /status
• GET /capabilities
• GET /help/security-logout
• GET /help/access-blocked
• GET /qr

Purpose

• runtime health and readiness checks
• version and compatibility negotiation
• maintenance-mode or availability checks
• capability discovery for public constants and access-token policy
• small help pages served by the backend
• QR code generation for client flows that need it

Client Guidance

• use version and version/negotiate before relying on new client features
• use capabilities for runtime feature hints instead of hardcoding assumptions
• use status and health for lightweight diagnostics
• treat help content as human-facing supplemental guidance, not machine API schema
• call /qr with data, and optionally size and format, when you need a locally generated QR image
