Choose this endpoint when you need a lightweight, on-demand currency conversion with a clear numeric result and exchange rate. It is ideal for single currency pair lookups rather than bulk or historical rate queries. At $0.01 USDC per call via x402, it is cost-effective for occasional agent-driven conversions in financial, travel, or invoicing workflows.
Side effects

- Missing required 'from' or 'to' query parameters causes a 400 bad request
- Amount of zero or negative value is rejected due to exclusiveMinimum constraint
- Exchange rate data source may be temporarily unavailable causing a 5xx error
- Render.com cold start may introduce initial latency on first call
