Roadmap — reserved seams

These endpoints are part of the documented API shape but have no backend behind them yet. Calling any of them always returns 501 NOT_IMPLEMENTED (never a fabricated success) — see Errors & rate limits. Don't build against them until they show up as live in this doc.

Endpoint	Status	Why
POST /api/v1/login/otp/request · /verify	501	No matching backend operation exists for one-time-code login yet.
GET/POST /api/v1/activities/mileage/{id}[/catalog|/cart|/checkout|/history]	501	The points/mileage service isn't built yet.
GET/POST /api/v1/activities/instant-win/{id}[/play|/results]	501	The instant-win service isn't built yet.

If your integration needs one of these before it ships, talk to your Thalamus Lite contact — this page will be updated the moment an endpoint goes live, and it will start returning real responses instead of 501 with no other change to its request/response shape.
