How to call private endpoints

First of all, please generate API keys, so you may start calling private endpoints.

❗️
After the exploration is completed, we highly recommend using signed requests option.

Header settings if a single API key is used

Header	Value	Description
`accept`	`application/json`	The client expects response data as JSON.
`content-type`	`application/json`	The client sends data as JSON in the request body.
`api-key`	`YOUR_API_KEY`	A single API keys string to authenticate.
`account`	`pro`	To identify your account as a PRO account (Only for PRO accounts).

Example. Get account balance using API key

const apiKey = "YOUR_API_KEY"; // put here your Api key

const url = "https://api.kuna.io";
const path = "/v4/private/getBalance"; // put here request path. To get your account balance: /v4/private/getBalance
const options = {
  method: "GET",
  headers: {
    accept: "application/json",
    "Content-Type": "application/json",
    "api-key": apiKey,
  },
};

fetch(url + path, options)
  .then((response) => response.json())
  .then((showResponse) => console.log(showResponse.data));

import requests

api_key = "YOUR_API_KEY"  # put here your Api key

url = "https://api.kuna.io"
path = "/v4/private/getBalance"  # put here request path. To get your account balance: /v4/private/getBalance
headers = {
    "accept": "application/json",
    "Content-Type": "application/json",
    "api-key": api_key,
}

request = requests.get(url + path, headers=headers)
print(request.json())

Example. Create order using API key

Here we used single api-key for authorization, no parameters, and we send this JSON in the request body:

const apiKey = "YOUR_API_KEY";

const url = "https://api.kuna.io";
const path = "/v4/order/private/create";
const body = {
  type: "Limit",
  orderSide: "Bid",
  pair: "TRX_UAH",
  quantity: "10.00",
  price: "2.062",
};

const options = {
  method: "POST",
  headers: {
    accept: "application/json",
    "Content-Type": "application/json",
    "api-key": apiKey,
  },
  body: JSON.stringify(body),
};

fetch(url + path, options)
  .then((response) => response.json())
  .then((showResponse) => console.log(showResponse.data));

import requests

api_key = "YOUR_API_KEY"

url = "https://api.kuna.io"
path = "/v4/order/private/create"
headers = {
    "accept": "application/json",
    "Content-Type": "application/json",
    "api-key": api_key,
}
body = {
    "type": "Limit",
    "orderSide": "Bid",
    "pair": "TRX_UAH",
    "quantity": "10.00",
    "price": "2.062",
}

request = requests.post(url + path, headers=headers, json=body)
print(request.json())

Header settings if public + private keys are used

Header	Value	Description
`accept`	`application/json`	The client expects response data as JSON.
`content-type`	`application/json`	The client sends data as JSON in the request body.
`nonce`	`NONCE`	Request Time Stamp. Put in Unix Time Stamp format in milliseconds (ms).
`public-key`	`YOUR_PUBLIC_KEY`	Public key (It is in the second field when generating keys) string to authenticate.
`signature`	`SIGNATURE`	Unique signature for your request. Check authorization section for more info.
`account`	`pro`	To identify your account as a PRO account (Only for PRO accounts).

Example. Get account balance using public + private keys

const crypto = require("crypto");

const publicKey = "YOUR_PUBLIC_KEY"; // put here your public key
const privateKey = "YOUR_PRIVATE_KEY"; // put here your private key

const url = "https://api.kuna.io";
const path = "/v4/private/getBalance";
const body = {}; // empty object for GET request

// Get UTC time in milliseconds
const nonce = +new Date(); // nonce is a number that is always higher than the previous request number
// Hashing signature
const signature = crypto
  .createHmac("sha384", privateKey)
  .update(`${path}${nonce}${JSON.stringify(body)}`)
  .digest("hex");

const options = {
  method: "GET",
  headers: {
    accept: "application/json",
    "Content-Type": "application/json",
    "public-key": publicKey,
    nonce: nonce.toString(),
    signature: signature,
  },
};

fetch(url + path, options)
  .then((response) => response.json())
  .then((showResponse) => console.log(showResponse.data));

import json
import requests
import time

import hmac

public_key = "YOUR_PUBLIC_KEY"  # put here your public key

body = {}  # empty object for GET request

# Get UTC time in milliseconds
nonce = str(int(time.time() * 1000))  # nonce is a number that is always higher than the previous request number
query_string = path + nonce + json.dumps(body)
# Hashing signature
signature = hmac.new(private_key.encode("utf-8"), query_string.encode("utf-8"), hashlib.sha384).hexdigest()

headers = {
    "accept": "application/json",
    "Content-Type": "application/json",
    "public-key": public_key,
    "nonce": nonce,
    "signature": signature,

request = requests.get(url + path, headers=headers, json=body)
print(request.json())

  .createHmac("sha384", privateKey)

    "Content-Type": "application/json",
    "public-key": publicKey,
    nonce: nonce.toString(),
    signature: signature,
