## Description

hello.js is a JavaScript REST API client and social media API wrapper designed for authenticating users and aggregating data across multiple social network providers. It provides a unified interface to standardize requests and response formats, allowing for consistent data retrieval from diverse external services.

The project implements a secure OAuth2 handshake process that utilizes a proxy-based credential masking system to hide private API keys from the client side. It includes a token manager that handles the full authentication lifecycle, including scope-based permission mapping and an automated token refresh mechanism to maintain continuous user sessions.

The library covers broad capability areas including social media data aggregation, user session management, and paginated data retrieval. It manages the exchange of consent codes for access tokens and uses marker-based pagination logic to fetch sequential pages of data.
