Service coverage

The generated catalog contains 228 operations across 33 services. gum supports more products than its top-level command list suggests because product coverage lives in operation IDs such as gmail.users.messages.list, drive.files.export, and sheets.spreadsheets.values.update.

bash

gum search "calendar events"
gum describe calendar.events.list

Use Operations by service when you want to start from a product page. Use Command index when you need CLI flags, aliases, and subcommands.

Covered families

Family	Examples
Workspace	Gmail, Calendar, Drive, Docs, Sheets, Slides, Tasks, Admin SDK, Vault, Chat, Meet, Classroom, Forms, Apps Script, People
Media and public APIs	YouTube, Photos Library, Search Console, Maps, Custom Search
Ads	Google Ads Keyword Planner, GAQL reporting, guarded mutations, conversion uploads, and Data Manager ingestion and request diagnostics
Bundled plugins	Flights, Scholar, Patents, Trends, YouTube transcripts

Some services require setup outside gum: enabled APIs on the OAuth project, Workspace admin privileges, Photos Library app configuration, Google Ads developer-token approval, an API key, or a Programmable Search Engine cx.

Detailed setup lives in auth guides, including the separate Data Manager OAuth setup. Service matrix records operation depth and dated live checks.

Why service pages matter

gcloud exposes many product-specific commands. gum uses fewer commands because the catalog is the product surface. The generated service pages close that lookup gap: each page lists operation IDs, risk class, auth strategy, and the command shape to use for the first call.
