IMPORTANT: This returns only tool names and descriptions, NOT parameter schemas. You MUST call TOOL_GET(tool_name) to retrieve the full inputSchema (required parameters, types, descriptions) before calling TOOL_CALL. Calling TOOL_CALL without first calling TOOL_GET will fail because you won't know the required parameters. Workflow: TOOL_LIST -> TOOL_GET(tool_name) -> TOOL_CALL(tool_name, arguments) ($0.02/call) - TOOL_GET: Get the full schema for one or more tools including all parameters. After discovering tools via TOOL_LIST, use this to get the complete parameter schema before calling the tool. You can provide either a single tool name or a list of tool names if you're unsure which one to use. ($0.02/call) - TOOL_CALL: Execute a tool by name with the provided arguments. IMPORTANT: You MUST call TOOL_GET(tool_name) first to retrieve the full parameter schema before calling this tool. The arguments must match the schema returned by TOOL_GET, including all required parameters. Calling without the correct arguments will result in errors. Workflow: TOOL_LIST -> TOOL_GET(tool_name) -> TOOL_CALL(tool_name, arguments) ($0.02/call) ## Get Started 1. Get an API key at https://alpha-vantage.on.xpay.sh/account/keys 2.
