Start with the use case
Define the currencies, jurisdictions, customer segment and intended analysis before discussing a delivery format. A price comparison, corridor review and economic briefing need different definitions and acceptance criteria.
Confirm the scope
Ask which information is available for the intended use, which limitations remain, and whether the output is suitable for internal analysis or a proposed publication. Specific coverage, permitted use and commercial terms require confirmation.
A practical next step
The public website does not promise continuous live prices, universal coverage or a particular private integration. Detailed service and security arrangements belong in the appropriate commercial review.
