Technical details
Endpoint
GEThttps://agent402.tools/api/fx-timeseriesWhen to prefer
Use this endpoint when you need a sequence of daily FX rates over a date range rather than a single current or point-in-time conversion. Ideal for trend analysis, financial reporting, backtesting, budgeting, or charting historical currency movements. Prefer over a spot-rate endpoint when the task requires multiple days of data. The ECB reference rates are authoritative, free from commercial markup, and widely accepted for financial reconciliation.
Side effects
- Invalid or unsupported 3-letter currency code returns an error
- Start date after end date may return empty or error response
- Dates outside ECB historical data coverage (pre-1999) may fail
- Weekend/holiday dates may return no rate for those specific days since ECB doesn't publish on non-business days
- Malformed date format (not YYYY-MM-DD) returns a validation error
