eBay API Client

The `ebay-api` package provides a comprehensive client library for interacting with both the Traditional (XML) and modern RESTful eBay APIs, supporting Node.js and browser environments. Currently at version 9.5.1, it offers robust functionality for accessing various eBay services, including Buy, Commerce, and others, with an active release cadence reflecting ongoing development and API updates. Key differentiators include built-in support for multiple authentication flows like client credentials grant, authorization code grant (OAuth2, Auth'N'Auth), and Digital Signatures, simplifying complex eBay authentication processes. It also ships with TypeScript types, enhancing developer experience and type safety for large-scale applications.
