Hello @anjanesh ,
Welcome to the forum!
It’s generally S3 replacement, but can be used as Dropbox with rclone (take a look on rclone mount too) or http://sliksafe.com/ if you want more features (many companies uses Storj DCS as a backend, this is one of them).
However, I would like to suggest to use a native protocol where is possible to do not skip reach features like a Client-side encryption (S3-compatible Gateway uses Server-side encryption), p2p for data transfer (useful with fast internet channel - more than 1Gbit, and your customers will download files from closest location directly from nodes, giving CDN-like features) and flexible Access Management.
See Storj Client Libraries | Storj Docs
Regarding linksharing - replace /s/ in the URL to /raw/.
