Value
A wehoop_data tibble, one row per record; the columns are always these, in this order
(sdv-py wjbl_roster):
| col_name | type | description |
| league_id | integer | Competition-edition id league_id (key space: W League competitions; sequential, ONE id per season of the league AND per all-star game, cup or camp: 45 = '25-26 W League', 47 = '26-27', 20 = '13-14', 46 = All-Star 2025-26). The league_id parameter of /play-schedules and /play-schedule-months; enumerate with /leagues.

Details
Unofficial and unsupported: these wrappers read the JSON backend of www.wjbl.org (api.wjbl.01core.app), keyless, found in the site's own JavaScript. The site's terms of use (www.wjbl.org/kiyaku/) forbid reproducing, republishing or otherwise using site content without permission: a copyright clause, not an anti-scraping one. The wrappers fetch on the user's behalf; a published data release or a hosted mirror needs the owner's decision first. The site has no robots.txt (404, checked 2026-10-12), so no Crawl-delay is published; the runtime waits at least 1 s before every request, retries included. Payloads are not redistributed as release assets.
Women's league: the W League is Japan's top women's basketball league (the SportsDataverse R counterpart is wehoop). All text is Japanese (team names, phases, play-by-play actions); the column descriptions translate the vocabulary.
Seasons are END years (2026 = 2025-26, 2000 = 1999-2000). The API keys a season edition by an opaque league_id (45 = '25-26 W League'; every all-star game, cup and camp has one too) and the wrappers map the END year with the live league list (one extra, cached request; END = 2000 + the second YY of league_title). Phases inside an edition (season_id: 169 = regular season Premier, 170 = Future, 176 = playoff final; two divisions from 2024-25) are native ids, passed as given: wjbl_standing_seasons lists them with their END year.
The schedule is paged by month: wjbl_schedule answers ONE month (game_month, YYYY-MM; omitted = the season's latest month only). List the months with wjbl_game_months and loop. The game routes take only the global play_schedule_id and serve final games only: each makes one extra, cached request (the game header) to prove the game is final and that the answer is the game and the teams asked for.
Errors are HTTP 200: an unknown id answers [] (wehoop_no_data) and a missing or non-numeric parameter answers an error envelope (wehoop_asset_fetch). Coverage: schedules from 1999-2000, box scores from 2013-14, play-by-play and the period stats from 2018-19 (earlier games answer [] on the /pbp routes: wehoop_no_data). No route carries shot coordinates.
Personal data: the organiser's contact details (phones, e-mail) and the player's blood type are never output, and phone numbers and e-mail addresses inside free text are replaced by [redacted-phone] / [redacted-email]. Do not add them back. Player bio fields and referee names are public and stay.
Errors are classed conditions, all inheriting
wehoop_error:wehoop_no_data(HTTP 404 or the API has nothing for the request: an empty list, an id it does not know, a game without play-by-play before 2018-19, a season without months or games),wehoop_bad_request(a season that is not the END year of a W League edition, an id that is not an integer or a game_month that is not YYYY-MM, raised before the request, or the API's HTTP 400 / 422) andwehoop_asset_fetch(any other failure: an error envelope at HTTP 200, any other non-2xx, an empty or non-JSON body, a game that is not final, a truncated play-by-play, or a body for another game, league edition, month, team, season phase or player than the one asked for;transientis TRUE for 408 / 429 / 5xx and transport failures). HTTP 500 is retried. Wrappers raise; they never warn and return an empty frame.
