This is a comprehensive Gmail API wrapper that handles the full email lifecycle through curl commands. It covers everything from basic inbox queries to thread management, drafts, filters, and even vacation settings. The examples are well-structured with proper RFC 2047 encoding for subjects and base64url formatting for message payloads. You get search with Gmail's query syntax, label management, attachment handling, and all the CRUD operations you'd expect. The troubleshooting section points you to zero doctor for auth issues. It's thorough enough that you won't need to context-switch to Google's docs for most common email automation tasks.
