"""
The code that would fit at $PLACEHOLDER$ is the definition of the router endpoints. Each endpoint corresponds to a specific HTTP method and URL path. The router is responsible for handling requests related to clients. It includes the following endpoints:

GET /clientes: Retrieves all clients from the database.
POST /clientes: Creates a new client in the database.
PUT /clientes: Updates an existing client in the database.
DELETE /clientes/{ID_Proveedor}: Deletes a client from the database based on the provided ID_Proveedor.
GET /clientes/buscar: Searches for clients based on the provided name or contact.
Each endpoint is wrapped in a try-except block to handle any exceptions that may occur during the database operations.
