Search Console summary (Growth+)

Google Search Console headline totals (impressions, clicks, ctr as a 0..1 fraction, average position) over a date range, with optional country/device breakdown. Requires a connected Search Console property (Growth+); otherwise ERR_SEARCH_CONSOLE_NOT_CONNECTED / ERR_PLAN_REQUIRED. Returns ERR_SEARCH_CONSOLE_ACCESS_REVOKED (403) when Google has revoked the connection's access (reconnect the property), and ERR_SEARCH_CONSOLE_UPSTREAM (503, with a Retry-After header) when Google Search Console is unavailable or over quota.
