No client can hold 400 tool definitions in every request without cost, and unlike Amplitude there is no documented progressive-discovery mode here. That does not make the surface useless — it makes the connection something to configure deliberately rather than leave on. The audit-trail tool is the one worth the trouble: knowing who changed a campaign and when is the question that follows every unexplained spend change.
GoMarble's endpoint for their ads analysis product. Their documentation enumerates roughly 400 tools, the largest surface in this directory, covering several advertising platforms per-tool rather than generically.
- List and inspect ad accounts, with business details, status and spend information
- Ad account insights — performance metrics and analytics for campaigns
- Account activities — an audit trail of every change made to accounts and campaigns
- Creative assets — the images, video and text used in ads, extracted for analysis
- And the rest of the roughly 400, across the supported platforms
