ManifestHub is a Steam Depot Manifest Cache that provides an API for accessing Steam depot manifests. The repository contains documentation and data files (appaccesstokens.json mapping depot IDs to access tokens) but does not include the actual application source code in the visible file tree. The service requires an API key, depot ID, and manifest ID to retrieve manifests via the endpoint https://api.manifesthub1.filegear-sg.me/manifest. Based on the README, it supports latest manifests and workshop manifests, with free API keys valid for 24 hours. The project appears to be actively maintained with recent commits.
