A marketplace engine for digital goods
with one-click purchase and an AI trend advisor
Our own marketplace engine: FastAPI backend, Next.js storefront, Telegram bot and Mini App, universal product model (keys, accounts, gift cards, subscriptions, services), instant delivery from encrypted stock, crypto and Telegram Stars payments, admin panel, reviews, promo codes, and a game-trends module with an AI advisor that sends reports to Telegram. 223 automated tests.
What it is
A complete marketplace for digital goods that works both as a website and inside Telegram. One product model covers keys, accounts, gift cards, subscriptions, VPS and services. Stock is encrypted at rest and delivered the moment payment confirms.
Features
Instant, manual, unlimited and external-API delivery modes; payments by crypto gateway, internal balance and Telegram Stars; one-click purchase without a cart; reviews, favourites, promo codes, refresh tokens; buyer-to-admin chat by order link; a full admin panel with statistics, orders and refunds; a competitors block fed by a marketplace catalogue API.
Trends module. Signals from Twitch (100 categories into 15 games and 7 currencies), IGDB (50 signals), Google Trends and the PlayStation Store, with a Claude-based advisor that writes what to stock next and sends the report to Telegram.
Why it matters
Every mechanic here was later reused: the delivery engine and the Stars payments in ProBay, the trends module in the pricing dashboard of a client. Building our own products is how we test what we sell.
