Examples

list_account_balances <account>

Script

import json
from grapheneapi import GrapheneAPI
client = GrapheneAPI("localhost", 8092, "", "")
res = client.list_account_balances("dan")
print(json.dumps(res,indent=4))

Result

[
    {
        "asset_id": "1.3.0",
        "amount": "331104701530"
    },
    {
        "asset_id": "1.3.511",
        "amount": 3844848635
    },
    {
        "asset_id": "1.3.427",
        "amount": 8638
    },
    {
        "asset_id": "1.3.536",
        "amount": 31957981
    }
]

transfer <from> <to> <amount> <asset> "<memo>" <broadcast>

Script

import json
from grapheneapi import GrapheneAPI
client = GrapheneAPI("localhost", 8092, "", "")
res = client.transfer("fromaccount","toaccount","10", "USD", "$10 gift", True);

The final parameter True states that the signed transaction will be broadcast. If this parameter is False the transaction will be signed but not broadcast, hence not executed.

transfer2 <from> <to> <amount> <asset> "<memo>"

Script

import json
from grapheneapi import GrapheneAPI
client = GrapheneAPI("localhost", 8092, "", "")
res = client.transfer2("fromaccount","toaccount","10", "USD", "$10 gift");
print(json.dumps(res,indent=4))

This method works just like transfer, except it always broadcasts and returns the transaction ID along with the signed transaction.
