## Overview

Klyra is an API marketplace: developers publish and manage APIs, discover and test offerings, and subscribe and pay; administrators oversee platform operations. The graph preserves the documented AI, analytics, review, and notification capabilities, though their implementations are not fully evidenced in the excerpts. The repository shows a React client and Express backend, with API-build and playground internals sampled. Several feature links are documented in the README rather than verified through sampled runtime wiring.

Main entry points: [`frontend/src/App.tsx`](https://github.com/mahidihasan/klyra/blob/main/frontend/src/App.tsx) (Marketplace client), [`backend/src/modules/api-build/api-build.routes.ts`](https://github.com/mahidihasan/klyra/blob/main/backend/src/modules/api-build/api-build.routes.ts) (API build routes), [`backend/src/modules/billing/billing.routes.ts`](https://github.com/mahidihasan/klyra/blob/main/backend/src/modules/billing/billing.routes.ts) (Billing routes), [`frontend/src/pages/AdminPanel/AdminEngineRoom.tsx`](https://github.com/mahidihasan/klyra/blob/main/frontend/src/pages/AdminPanel/AdminEngineRoom.tsx) (Admin console)
