Search for available trading pairs containing a specific cryptocurrency
AI agents call search_symbols to retrieve information from Crypto 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 and queries data about available trading pairs without creating, modifying, deleting, or executing operations. It is a passive information lookup similar to the other sibling tools (get_crypto_price, get_historical_data, get_market_summary) which are all data retrieval functions.
From the tool's definition Tool description states 'Search for available trading pairs' - a read-only query operation with no data modification or external side effects. The function searches and retrieves information from the cryptocurrency market data provider.
