## Overview

This repository appears to implement a music-streaming platform with listener, creator, advertiser, and admin experiences. The principal workflow is a client request routed to API controllers, which access catalog and account data and return API resources; listeners also have library, discovery, and playback-related features. The tree indicates subscription payments, advertising, audio transcoding, and moderation as additional capabilities. Source excerpts and the index support some internal links, but many feature implementations were not sampled, so uncertain flows are omitted.

Main entry points: [`routes/api.php`](https://github.com/saudexgpt/altar-place-backend/blob/main/routes/api.php) (API routing), [`resources/js/app.js`](https://github.com/saudexgpt/altar-place-backend/blob/main/resources/js/app.js) (Vue application), [`app/Http/Controllers/Api/CatalogController.php`](https://github.com/saudexgpt/altar-place-backend/blob/main/app/Http/Controllers/Api/CatalogController.php) (Catalog and discovery), [`app/Http/Controllers/Api/LibraryController.php`](https://github.com/saudexgpt/altar-place-backend/blob/main/app/Http/Controllers/Api/LibraryController.php) (Listener library)
