All three providers support player research. ESPN and Fantrax contribute native data; linked ESPN and Sleeper feeds add public research where a player can be matched. Coverage varies by sport and player. Public preset projections are separate from league-scored points. Historical research is opt-in, and unavailable fields are identified explicitly.

Every tool listed here retrieves or analyzes league data. No write-action tools are registered, so League Loom cannot change your lineup or your account. Your AI only sees the tools your connected platforms can serve: a capability-gated tool appears only when at least one platform supports it.
Ready-made questions that call these tools are in the prompt library, setup and safety answers are in the FAQ, and changes to this list are recorded in the release notes. Use of the connector is covered by the terms of service.
