Why League Loom
Fantasy basketball advice is useful when it reflects your roster, category or points scoring, and place in the standings. Generic rankings do not know which categories you are punting or who is already on your bench.
League Loom connects ESPN, Sleeper, or Fantrax through OAuth with Dynamic Client Registration and PKCE, so Claude or ChatGPT can use live league data. Ask who is trending on waivers, where a matchup is turning by category, or how a Fantrax trade affects your salary cap.
League Loom also supports Fantrax NBA and college basketball leagues; no write-action tools are registered today.
