get_api_reference
Get the per-class API reference for an amCharts 5 class — the class page PLUS its settings table (with DEFAULTS) and, optionally, its private/read-only settings. This is the authoritative source for exact setting names and default values (e.g. tooltip background cornerRadius, axis tick visible default). Pass a class name in any casing, e.g. 'XYCursor', 'Tooltip', 'PieSeries', 'AxisRendererX'.
