Verify webhook signature from Infini.
AI agents call verify_webhook_signature to retrieve information from Infini Payment MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a cryptographic verification operation on webhook signatures—a read-only security check that retrieves/validates data without side effects, creating new transactions, executing arbitrary code, or deleting records. It does not move funds, modify payment orders, or trigger external operations with uncontrolled effects.
From the tool's definition Tool name 'verify_webhook_signature' and description 'Verify webhook signature from Infini' indicate a verification/validation operation that checks the authenticity of incoming webhook data without modifying or executing payment logic.
