Costs vary based on the AI model used and the number of tokens processed. You can use OpenAI, Anthropic, or any OpenAI-compatible endpoint. You pay directly to your chosen AI provider for each API request.
• Stripe – Charges a transaction fee of 2.9% plus $0.30 per successful payment transaction when users purchase credits.
• MongoDB – Free tier available for development with 512MB storage. Production use may require a paid plan based on storage, bandwidth, and usage. MongoDB Atlas offers a free tier suitable for small applications. Check MongoDB Atlas 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.
