"""Fetch Valve Immortal regional leaderboards into data/leaderboards.json.
|
|
|
|
Pulls the official division boards (americas / europe / se_asia / china) and
|
|
keeps Top 100 per region for the Climperor web「排行」page.
|
|
|
|
Valve does not expose MMR or account_id on this endpoint — only rank, name,
|
|
and optional team/country. Divisions use separate MMR scales (no global board).
|
|
|
|
Preview only — do not merge into relations/heroes or recommend.
|
|
|
|
Usage:
|
|
python fetch_leaderboards.py
|
|
python fetch_leaderboards.py --out data/leaderboards.json
