FAQ

Do I need an API key?

No. The Sleeper API is read-only for public league and draft data.

Is this for redraft or dynasty?

Both. Tools support common formats, and value sources adapt to your settings.

Does loading a portfolio require a Sleeper password?

No. Sleeper portfolios use public, read-only data. An optional Arsenal account is the separate secure sign-in for cloud saves and your profile.

Why is the draft pick tracker useful?

It shows multi-league drafting at a glance: on-deck alerts, pace-based ETA, and recent pick runs.
