Do I need an account?
Browsing is open
You can read the directory, page through it, and see every metric on every listing without an account. Nothing about a listing's evidence is gated behind a signup.
Revealing isn't
A reveal is counted once per listing, per account, forever. That accounting needs an account to attach to, so revealing a name means signing in. A free account takes an email address and no card.
What the account gives you
Your reveals, remembered: a name you have opened stays open to you. Your plan and your usage for the current month live there too, alongside API keys on Business.
