What a Sleeper username gives the analyzer
Sleeper's public API exposes every league a user is in, with rosters, standings, the schedule, traded picks and the full transaction history. The analyzer reads all of it read-only, prices every roster with live dynasty values adjusted to each league's format, and reads each team's age curve to place it on the contend-or-rebuild spectrum.
Reading is free, acting is optional
Everything on this page works from the username alone. Verifying the Sleeper account adds the write side: submitting lineups, waiver claims and trade offers from Dynasty Command, paced to Sleeper's limits. The analysis is the same either way.
