📝 General Notes
- Base Currency: The currency against which all other rates are quoted by the provider. LibreFolio automatically handles conversions between any pair, regardless of the provider's base currency.
- Update Frequency: ECB, FED and BOE update their rates once per business day (weekdays only). The SNB publishes monthly averages only, stored on the 1st of each month.
- No API Keys: All core providers use publicly accessible APIs — no registration or API keys required.
