Get a UGF quote for a specific payment coin and chain. Checks wallet balance against quote amount and returns whether the agent can proceed.
AI agents call ugf_quote to retrieve information from Universal Gas Framework 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 pricing information and validates balance eligibility without executing transactions, modifying data, or committing financial obligations. It is a prerequisite check before transaction execution, not the execution itself.
From the tool's definition Tool description states it 'Get[s] a UGF quote' and 'Checks wallet balance against quote amount and returns whether the agent can proceed.' The verb 'get' and 'checks' indicate read-only data retrieval with no state modification.
