📚 Reference Data
Channel activity and the read-only lookup lists — categories, languages, regions, abuse reasons, and memberships.
Seven tools, all read-only and all 1 quota unit per call. Six are static/near-static lookup lists useful for populating the enum-like fields other tools accept; one (list-activities) is a live feed of channel activity.
| Tool | Quota cost | Notes |
|---|---|---|
list-activities | 1 unit | Uploads, likes, playlist adds, etc. |
list-video-categories | 1 unit | Assignable categories for a region |
list-i18n-languages | 1 unit | Application languages YouTube supports |
list-i18n-regions | 1 unit | Content regions YouTube supports |
list-video-abuse-report-reasons | 1 unit | Valid reasonIds for report-video-abuse |
list-members | 1 unit | Monetisation-gated |
list-membership-levels | 1 unit | Monetisation-gated |
list-activities
Reads recent channel activity (uploads, likes, playlist additions, subscriptions, and more) for a channel, or your own if channelId is omitted.
Lookup lists
list-video-categories (filtered by regionCode, default US), list-i18n-languages, and list-i18n-regions return the reference data YouTube itself uses to populate category pickers and language/region selectors. list-video-abuse-report-reasons returns the reasonId/secondaryReasonId values accepted by report-video-abuse.
Removed from the API:
guideCategories.listno longer exists — YouTube deprecated and removed the GuideCategories resource, and it isn't present in the currentgoogleapisclient. There's no replacement to wrap.
list-members / list-membership-levels
⚠️ Monetisation-gated. Both tools call endpoints that require an active YouTube Partner Program channel with channel memberships enabled — on any other channel they return a 403. list-members lists people who are members of your channel; list-membership-levels lists the pricing tiers you've configured.
