# Astral

> Astral is a private-link file-sharing service. Signed-in people upload files up to their plan limit (10–500 MiB), choose a finite lifetime up to 365 days (or Forever on Aether), and share an optionally access-controlled URL.

Astral exposes a server-to-server REST API with quota-reserved one-time upload sessions, active-file management, public metadata and statistics, a small JavaScript SDK and CLI, and a stateless Model Context Protocol endpoint.
