★ = directly verified during this investigation (Oct 11–12, 2026). Unmarked items are community-documented leads, not yet re-verified.

## TransJakarta services

- ★ `https://tijeapi.transjakarta.co.id` — official app ("TJ:Transjakarta" / Tije) REST backend. Guest login works: `POST /v1/auth/login/guest`. (~105 endpoints total per open-tj; only the bus endpoints verified here.)
- ★ `wss://mqtt.tj.co.id:8084/mqtt` — live bus feed; MQTT 3.1.1 over WebSocket Secure, anonymous access.
- ★ `https://gtfs.transjakarta.co.id/files/file_gtfs.zip` — official GTFS zip (~2.4 MB). Portal UI is login-gated; the file URL itself is open. Version observed: 27 Jul 2026.
- ★ `https://bustrack.transjakarta.co.id` — TJ's own tracker web app, built on Traccar (stock UI + API surface). `/api/session` returned 404; access looks restricted. Separate system from the Tije feed.
- `https://chatbot.transjakarta.co.id/ws/` — "Tara" AI chatbot WebSocket (JWT) — documented by open-tj.
- `https://tije-dashboard.transjakarta.co.id` — login page for the app's admin dashboard.

## Third-party projects (how the stack became known)

- `https://github.com/mugnimaestra/tj-live` — SvelteKit tracker. Source documents broker URL, guest JWT flow, `POST /v1/bus` topics, Bus schema.

## Investigation target (origin of this research)

- `https://transit.oyenza.com` — "Bus Jakarta Live", independent third-party tracker ("Tidak berafiliasi" — not affiliated). Serves TransJakarta's feed through its own backend:
  - browser stream `wss://transit.oyenza.com/api/live` (custom protocol)
  - REST: `/api/bus/<fleet-no>`, `/api/halte/<stop-id>`, `/api/stats`, `/api/meta`, `/api/places`
  - `static.json` cites the official GTFS URL as its static source
- Related domains: `transit.vantis.sh` (alias), `vantis.sh`, `oyenza.com` — same developer.
