What zap-list-transactions does on Nostr Bray
AI agents call zap-list-transactions to retrieve information from Nostr Bray without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why zap-list-transactions is rated Low
This tool queries and retrieves transaction history via Nostr Wallet Connect (NWC). It does not initiate payments, modify wallet state, or execute financial operations—it only reads transaction records. While the data is financial in nature, the operation itself is a passive read with no side effects or ability to move funds.
From the tool's definition Tool name uses 'list' (passive retrieval verb) and description states 'List recent Lightning transactions' — a query operation that retrieves historical data without modification or execution of payments.
