Get full options chain data for a ticker, including GEX, OI, and volume by strike
AI agents call get_options_chain to retrieve information from Sellthenews without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and queries options market data without creating, modifying, deleting, or executing operations. It has no side effects on external systems or financial positions. The read-only nature of the server and the descriptive language (get, analyze, retrieve) confirm this is a safe information-retrieval function with minimal security risk.
