Get a trader
AI agents call get_trader_profile to retrieve information from Predictfun without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns trader profile data from the Predict.fun protocol without side effects. It is a read-only retrieval operation similar to sibling tools like 'get_leaderboard' and 'find_trader_persona'. The low severity reflects minimal blast radius — exposure of trader profile data carries privacy concerns but no financial loss, irreversible harm, or code execution risk.
From the tool's definition Tool name 'get_trader_profile' and description 'Get a trader' indicate data retrieval only. In context of a prediction market platform, this retrieves trader information/statistics from the protocol.
