    Representative OpenAPI description of RevenueCat's public REST surface. It
    covers the v1 REST API (https://api.revenuecat.com/v1) for subscribers,
    receipts/purchases, entitlements, offerings, and subscriber attributes, and
    the v2 REST API (https://api.revenuecat.com/v2) for projects, apps,
