When to prefer

Choose this endpoint when you need currency conversion with a built-in cryptographic audit trail, particularly in regulated, financial, or compliance-sensitive workflows. Prefer it when you need verifiable, tamper-evident conversion records rather than a plain exchange-rate lookup. Also suited for AI agents operating across the 27 countries Strale supports, where trust and auditability of financial calculations matter.
