Distinct symbols traded on one venue, ordered alphabetically, as a flat array of strings. Gated by the key plan (an unentitled venue returns 403); metadata only, not metered. KRAKEN ALIASES: kraken spells bitcoin XBT and dogecoin XDG, so this list also contains the BTC/DOGE spellings of those pairs (BTCUSD alongside XBTUSD, ETHBTC alongside ETHXBT) and both spellings are accepted as the symbol of any data request. LIMITS: the responses always echo the spelling YOU sent, never a rewritten one, and the quoteAsset COLUMN still reads "XBT" on the kraken pairs quoted in bitcoin. This is a single venue renaming two assets and nothing more: it does NOT make one symbol string work across venues, because the nine venues use three different separator conventions (dash on coinbase/kucoin/okx, underscore on gate, none elsewhere).
