Τα API μας REST και WebSocket χρησιμοποιούν ελαφρώς διαφορετικά σύμβολα για να αναπαραστήσουν τις ίδιες υποκείμενες αγορές (τα ίδια ζεύγη νομισμάτων), οπότε είναι μερικές φορές απαραίτητο να μεταφράζονται τα σύμβολα εμπρός και πίσω μεταξύ των διαφορετικών εκδόσεων.
Τα τελικά σημεία (endpoints) REST Assets και AssetPairs μπορούν να χρησιμοποιηθούν για την ανάκτηση μιας λίστας όλων των διαθέσιμων νομισμάτων και ζευγών νομισμάτων (αγορών), μαζί με όλες τις πιθανές εκδόσεις συμβόλων για κάθε αγορά.
Για παράδειγμα, η κλήση του τελικού σημείου REST Assets ως https://api.kraken.com/0/public/Assets θα επέστρεφε μια απάντηση παρόμοια με την ακόλουθη:
Bash

Ομοίως, η κλήση του τελικού σημείου REST AssetPairs ως https://api.kraken.com/0/public/AssetPairs θα επέστρεφε μια απάντηση όπως η ακόλουθη:

Ένα ticker είναι μια αναφορά των τρεχουσών τιμών αγοράς για ένα μεμονωμένο ζεύγος νομισμάτων και περιλαμβάνει όλες τις ακόλουθες πληροφορίες:
πιο πρόσφατη τιμή συναλλαγής
πιο πρόσφατος όγκος συναλλαγών
καλύτερη (υψηλότερη) τιμή προσφοράς (bid)
διαθέσιμος όγκος στην καλύτερη τιμή προσφοράς (bid)
καλύτερη (χαμηλότερη) τιμή ζήτησης (ask)
διαθέσιμος όγκος στην καλύτερη τιμή ζήτησης (ask)
πρόσθετες πληροφορίες συναλλαγών (υψηλό/χαμηλό ημέρας, αριθμός συναλλαγών, συνολικός όγκος ημέρας, κ.λπ.)
Το τελικό σημείο REST Ticker μπορεί να χρησιμοποιηθεί για την ανάκτηση δεδομένων ticker για ένα μεμονωμένο ζεύγος νομισμάτων, μια ομάδα ζευγών νομισμάτων ή όλες τις αγορές που προσφέρει επί του παρόντος η Kraken.
Για παράδειγμα, η κλήση του τελικού σημείου Ticker ως https://api.kraken.com/0/public/Ticker?pair=xdgusd θα επέστρεφε τα τρέχοντα δεδομένα ticker αποκλειστικά για την αγορά Dogecoin/USD, όπως:
