About this API

Kraken is a US crypto exchange founded in 2011, one of the originals — a year before Coinbase, 6 years before Binance. Differentiator is stability and reliability: 11 years without being hacked (rare in crypto), high-quality customer service (many crypto exchanges suffer from automated CS), preferred by institutions and old-money players. Rich fiat onramp — beyond USD also supports EUR/GBP/CAD/AUD/CHF and other major fiats; European users particularly like it. API design is somewhat dated (pairs use XBTUSD instead of BTCUSD, idiosyncratic naming) but stable. Note: tight rate limits (Basic 15 calls/min); high-frequency trading needs tier upgrade or WebSocket.

Why is the pair named XBT instead of BTC?+
