/**
 * Latest central bank policy interest rates (free tier — counts against the normal daily request quota). Covers the ~40 live central banks in the BIS central bank policy rates dataset (Fed, ECB, BoE, BoJ, PBoC, RBA, BoC, SNB, RBI, BCB and more). Without `country` returns every live series; with `country` accepts ISO country codes (US, GB, JP) or currency codes (USD, GBP, JPY), comma-separated. EUR (or EU/EZ/ECB) returns the ECB rate; a euro-area member (e.g. DE) with no live national series also resolves to the ECB. `rate` is in percent; `effective_date` is the first day the BIS series shows the current rate; `as_of` is the latest BIS observation date; `definition` is the BIS description of which rate is used (e.g. the US figure is the mid-point of the Fed Funds target range).
