I need a complete web platform where visitors can sign up with a simple email-and-password flow, browse a catalogue of my Gaming APIs, purchase access using cryptocurrency, and immediately receive the credentials they need to start calling the endpoints. Core flow 1. Registration & login handled through a secure email/password system (no social or 2FA at this stage). 2. Product pages listing each Gaming API with pricing tiers and basic usage docs. 3. Checkout that accepts the leading crypto payment gateways and, upon confirmed payment, automatically provisions an API key. 4. A lightweight user dashboard showing active subscriptions, remaining quota, basic call analytics and a quick “regenerate key” button. 5. Admin area for me to upload new API plans, set prices, view orders, revoke keys and download reports. Tech stack is flexible as long as you deliver clean, well-documented code and a deployable package (frontend, backend, database, payment integration). REST is fine, but if you prefer GraphQL for internal calls just outline why. Deliverables • Full source code in a private repo • Setup instructions and database schema • Tested crypto payment integration in sandbox and live modes • Postman (or similar) collection showing key endpoints • Brief hand-off call or video walkthrough If you have past work on API marketplaces or blockchain payment flows, please share a link.
