Example use cases
Quarterly finance report reconciliation
“I need the historical exchange rates from GBP to USD for the entire fourth quarter of 2023 — October 1 through December 31 — so I can reconcile our overseas revenue figures.”
Travel budget planning analysis
“What were the exchange rates from USD to JPY between March 1, 2025 and March 15, 2025? I'm trying to understand how much my Japan trip actually cost me day by day.”
Currency trend analysis for investment
“Can you fetch the EUR to CHF exchange rate history from January 1, 2024 to June 30, 2024 so I can see how the Swiss franc trended against the euro in the first half of last year?”

Endpoint
POSThttps://twin.unykorn.org/records/fx-history?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need historical FX rate data across a date range rather than a live or single-point rate. It is well-suited for financial reporting, budget reconciliation, trend analysis, or any workflow that needs day-by-day or period-by-period exchange rate history between two specific currencies.
Side effects
- Invalid or unsupported currency code returns an error
- Start date after end date returns a validation error
- Date range exceeding supported history window may return partial or empty results
- Malformed date format (not YYYY-MM-DD) causes a parse error
- Very large date ranges may return truncated data or timeout
