• remove redundant paths i.e. /api/Changelogs/GetChangelogs -> /api/Changelogs
• add "v2" in url: i.e. /api/v2/*
• remove redundant data not displayed on the page. i.e. CustomUserAgent in /api/Sources/GetSource?sourceName=x
• document OpenAPI for all methods
• use [Required] & other attributes to validate the input
