⚠️ Important: External API Costs Disclaimer
Please note that this application requires external API services to function, and you will incur costs based on your usage of these services.
This application integrates with several third-party services that charge fees based on usage:

- Stripe – Charges a transaction fee of 2.9% plus $0.30 per successful payment transaction when users purchase credits.
- Supabase – Free tier available for development with 500MB database storage and 50,000 monthly active users. Production use may require a paid plan based on storage, bandwidth, and usage. Check Supabase pricing for current rates.
You are responsible for all costs associated with these external services. The purchase price of this application includes only the source code and does not include any API credits, service subscriptions, or usage fees. Before deploying this application, please review the pricing pages of all required services to understand the costs you will incur based on your expected usage volume.
While many services offer free tiers suitable for development and testing, production use will require paid plans. Ensure you have budgeted for ongoing API costs based on your expected user base and usage patterns.
