Call an extended tool
arena_call_extendedGateway to the EXTENDED tools of this server — listed here in one line each instead of individually, to keep the tool list short. Use it when no listed tool fits: per-metric daily history series, subscriptions, chart images, niche primitives. mode="call" runs the tool with arguments (same result, auth, tier and rate limits as calling it directly); mode="describe" returns its full description and parameters first, if the arguments are unclear.
