AI agents call get_payment_link to retrieve information from Filevine without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries an existing payment link without initiating any financial obligation, transaction, or money movement. It is a read-only operation that fetches data. The Financial category applies only to tools that actually move money or commit financial obligations (e.g., approve_invoice, process_payment). Generating or retrieving a link for later use does not itself constitute a financial action.
From the tool's definition Tool name 'get_payment_link' and description 'Get the online payment link for a project' indicate retrieval of a payment link URL, not execution of payment or financial transaction.
