工具（5）
🔴currencylayer_get_live_rates(currencies, source)
SPENDS 1 request of your currencylayer monthly quota per call (also when it fails after authentication; it is never retried). Real-time exchange rates for up to 174 world currencies and precious metals relative to a source currency (default USD). Quotes are keyed by pair, e.g. USDEUR = 0.918 means 1 USD = 0.918 EUR. The free plan refreshes daily, higher plans hourly down to every 60 seconds. Use 'currencies' to limit the reply. GET /live.

}🔴currencylayer_get_historical_rates(date, currencies, source)
SPENDS 1 request of your currencylayer monthly quota per call (also when it fails after authentication; it is never retried). Exchange rates for one past date (data back to 1999 for most currencies; a currency added later has no data before its start date and the whole request then fails). Quotes are keyed by pair, e.g. USDEUR. Use 'currencies' to limit the reply. GET /historical.

}🔴currencylayer_get_timeframe_rates(start_date, end_date, currencies, source)
SPENDS 1 request of your currencylayer monthly quota per call (also when it fails after authentication; it is never retried). Daily exchange rates for every date from start_date to end_date (at most 365 days apart), one entry per date. Needs the Enterprise plan or higher. The reply must stay small: days x currencies may not exceed 2000 (without 'currencies' that is 174 per day), checked before the request is sent. GET /timeframe.

}🔴currencylayer_get_rate_changes(start_date, end_date, currencies, source)
SPENDS 1 request of your currencylayer monthly quota per call (also when it fails after authentication; it is never retried). How exchange rates changed between two dates: per currency pair the start_rate, end_rate, absolute change and change_pct. Pass both dates or none (none = yesterday's end-of-day rate against the latest rate). Forex markets are closed on weekends, so a weekend change can be zero. Needs the Enterprise+ plan or higher. GET /change.
