Web analytics query format (Growth+)

How to query the web analytics provider connected to the project, live: the provider, the property every query runs on, the native query format it accepts, the allowed top-level fields, the rules the bridge enforces (the connected property is always used, only reads run, row limits), a worked example and, where the provider offers it, its live field list. Cached for an hour. Supported providers: Google Analytics 4, Adobe Analytics or Customer Journey Analytics, Matomo, PostHog, Plausible and Piano, connected on the AI Traffic page. Requires the Growth plan or above; otherwise ERR_PLAN_REQUIRED. Without a connected provider returns ERR_WEB_ANALYTICS_NOT_CONNECTED (404); a provider that refuses the stored credentials returns ERR_WEB_ANALYTICS_ACCESS_REVOKED (403); an unavailable provider, an exhausted provider quota, more than 20 uncached queries a minute or too many running at once for the project returns ERR_WEB_ANALYTICS_UPSTREAM (503): wait for the number of seconds in Retry-After before retrying.
