  3. * Viseca Shopper UI — bridge server
  4. *
  5. * Zero-dependency Node HTTP server that:
  6. * 1. serves the static UI from ./public
  7. * 2. proxies chat messages to the viseca-shopper OpenClaw agent via the
  8. * Gateway CLI: openclaw agent --agent <id> --session-key <key> --json -m <msg>
  9. * 3. multi-user: registration/login (scrypt + cookie sessions), per-user agent
  10. * sessions, subscription plans with daily message caps (accounts.js)
  11. * 4. external surfaces: bearer API keys, POST /api/v1/chat (plain JSON for
  12. * ChatGPT Actions & skills), /.well-known/ai-plugin.json + /openapi.json
  13. * 5. persistence: per-user chat history (GET/DELETE /api/history) survives
  14. * reloads; signed order policies are mapped to accounts and listed via
  15. * GET /api/policies with receipt status
  16. * 6. shopping controls (shopping.js): per-account spend cap, website
  17. * whitelist, Visa/Mastercard vault. Enforced at /api/policy/sign; the
  18. * chosen card is filed as policies/<id>.payment.json for the agent.
  19. *
  20. * Config (env):
  21. * PORT default 8794
  22. * HOST default 127.0.0.1
  23. * OPENCLAW_AGENT default viseca-shopper
  24. * OPENCLAW_SESSION default webui (base; users get <base>-u<id>)
  25. * OPENCLAW_BIN default openclaw
  26. * OPENCLAW_TIMEOUT_MS default 600000
  27. * AGENT_MAX_CONCURRENT default 2 (global agent-turn slots across users)
  28. * PUBLIC_BASE_URL default derived (x-forwarded-proto/host) — plugin manifest
  29. * REGISTRATION_OPEN default true ("false" closes signup)
  30. * PLANS_JSON optional override of plan caps, e.g. '{"free":{"daily":2}}'
  31. * ACCOUNTS_DATA_DIR default ./data
  32. * OPENCLAW_MODEL optional model override passed as --model to every agent turn
