Livraria API is a Spring REST backend for managing authors, publishers and books. A client sends JSON requests to resource controllers; controllers map request data, invoke services, and map results into responses. Services enforce catalog rules and use Spring Data repositories to read and write JPA entities in the configured H2 database. The README also describes customers and orders, but no corresponding source modules appear in the supplied tree, so those capabilities are not represented as implemented components. Wiring reflects sampled controllers and services; unsampled areas are not inferred.
