Get app B3TR action leaderboard via /api/v1/b3tr/actions/leaderboards/apps. Optionally filter by roundId OR date (yyyy-MM-dd UTC) but not both — they are mutually exclusive. Sort by totalRewardAmount or actionsRewarded; supports cursor pagination.
AI agents call getB3TRAppsLeaderboard to retrieve information from VeChain MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though getB3TRAppsLeaderboard only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
