API-symboler och tickrar

Symboler
Våra REST- och WebSocket-API:er använder något olika symboler för att representera samma underliggande marknader (samma valutapar), så det är ibland nödvändigt att översätta symbolerna fram och tillbaka mellan de olika versionerna.
REST-slutpunkterna Assets och AssetPairs kan användas för att hämta en lista över alla tillgängliga valutor och valutapar (marknader), tillsammans med alla möjliga symbolversioner för varje marknad.
Till exempel skulle ett anrop till REST-slutpunkten Assets som https://api.kraken.com/0/public/Assets returnera ett svar som liknar följande:
Bash

På samma sätt skulle ett anrop till REST-slutpunkten AssetPairs som https://api.kraken.com/0/public/AssetPairs returnera ett svar som följande:

Tickrar
En ticker är en rapport över aktuella marknadspriser för ett enskilt valutapar och innehåller all följande information:
- •
senast handlade pris
- •
senast handlade volym
- •
bästa (högsta) köpkurs
- •
volym tillgänglig till bästa köpkurs
- •
bästa (lägsta) säljkurs
- •
volym tillgänglig till bästa säljkurs
- •
ytterligare handelsinformation (dagens högsta/lägsta, antal affärer, dagens totala volym, etc.)
REST Ticker-slutpunkten kan användas för att hämta tickerdata för ett enskilt valutapar, en grupp valutapar eller alla marknader som Kraken för närvarande erbjuder.
Till exempel skulle ett anrop till Ticker-slutpunkten som https://api.kraken.com/0/public/Ticker?pair=xdgusd returnera aktuella tickerdata enbart för Dogecoin/USD-marknaden, såsom:
