Get real-time government bond data for a specific country.
AI agents call get_bond_info to retrieve information from Marketstack MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves financial market data (government bond information) without side effects. It queries and returns data without creating, modifying, deleting, or executing operations.
