Keepa
You do not need Keepa for release 0.1.
Release 0.1 reads your own Amazon account and nothing else. Keepa supplies price and rank history for products you do not yet own, which matters for sourcing decisions rather than for understanding what you already sell. Sourcing is deliberately out of 0.1.
This page exists so the answer to “do I need to buy a Keepa subscription before I start?” is findable, and the answer is no.
When sourcing arrives
Section titled “When sourcing arrives”You will supply your own Keepa key the same way you supply your own Amazon keys. The token cost will be yours rather than resold, which also means your sourcing scans are limited by your own plan and not by someone else’s quota.
The Sourcing report describes what that part of the system does, if you want to judge it before it ships.
