This API provides bulk transaction data for a wallet address in a 15-minute time bucket interval
AI agents call getBulkTransactions to retrieve information from Somnia MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves historical blockchain transaction data for a specified wallet address. It performs a passive data lookup operation without side effects—no transactions are created, modified, deleted, or executed. The 15-minute time bucket interval is a read-only retrieval parameter.
From the tool's definition Tool retrieves bulk transaction data with no mention of modification, deletion, or execution capabilities. Description states it 'provides bulk transaction data' and 'retrieves' historical transaction information from a wallet address in time intervals.
