Polar keeps the vibe indie. Challenge MMR keeps the score honest.
1. Open Polar → Settings → Access tokens / API.
2. Mint a token with read scopes only (subscriptions, products, orders).
3. Name it Challenge MMR so audits stay chill.
4. Paste it on your project card. We normalize recurring revenue to monthly EUR.
Write scopes? Hard pass. Read-only or nothing.
We refuse write-capable tokens. Read-only Polar access only.
