We are excited to introduce Korbit's new Open API service! With this service, you can freely access a variety of cryptocurrency exchange functions, including price inquiries, orders, deposits, and withdrawals, all through our Open API.
Any Korbit member can utilize the Korbit Open API to develop their own programs or send API requests, integrating their cryptocurrency trading strategies with the exchange.
For the latest news and detailed information about the Open API, please visit our Developer Center. Start using the Korbit Open API today to implement your own programs and strategies!
https://api.korbit.co.krwss://ws-api.korbit.co.kr/v2/public (Public Type)
wss://ws-api.korbit.co.kr/v2/private (Private Type)To use the Korbit Open API, you need to generate an API key. Any Korbit member can create an API key through the Korbit Developers.
When creating an API key, you can choose between two authentication signature methods: HMAC-SHA256 and ED25519.
HMAC-SHA256: Korbit generates the secret key required for signing and provides it to the user.
ED25519: The user generates an ED25519 key pair (public key and private key) and provides the public key to Korbit during the API key creation process.
For subsequent Open API usage, the user must send API requests signed with the method corresponding to their API key.
HMAC-SHA256: Convenient because Korbit generates the secret key for you. (Korbit securely encrypts and stores your secret key.)
ED25519: Requires the user to generate their own ED25519 key pair, which can be cumbersome but offers the advantage of enhanced security since the private key is not exposed.
For more detailed information, please refer to the Korbit Developers.
import { generateKeyPairSync } from "crypto";
const { publicKey, privateKey } = generateKeyPairSync("ed25519", {
publicKeyEncoding: {
type: "spki",
format: "pem",
},
privateKeyEncoding: {
type: "pkcs8",
format: "pem",
},
});
// Public Key (PKIX Format), Private Key (PKCS #8 Format)
console.log(publicKey, privateKey);# Private Key
openssl genpkey -algorithm ED25519 -out private_key.pem
# Public Key
openssl pkey -in private_key.pem -pubout -out public_key.pemYou can modify the permissions and other settings of your API key or delete it through the Korbit Developers. An API key is valid for one year from the date of creation, and the available functions vary depending on the permissions set. For instance, to place or cancel orders, you need an API key with the Order Placement permission.
Additionally, each API key can be restricted to specific IP addresses (up to a maximum of 20), which can also be configured in the Developer Center.
When you add, modify, or delete API keys, it may take up to 1 minute for the changes to be applied.
To use the REST API, you need to send HTTP requests to the Open API server (https://api.korbit.co.kr).
For GET and DELETE method requests, include the values in the URL query string. For POST method requests, include the values in the request body using the application/x-www-form-urlencoded format. The order of the input variables does not matter.
API responses are provided in JSON format, and the time is given in UNIX timestamp (in milliseconds).
Public APIs, such as quotation APIs, are open for anyone to use without an API key or authentication.
Private APIs, such as orders, assets, and deposits/withdrawals APIs, are available to Korbit members through their accounts. To use these, you need to obtain an API key and send authenticated API requests signed accordingly.
The accessibility of the private APIs depends on the seven permissions you can set for each API key: Asset Inquiry, Order Inquiry, Order Placement, Deposit Inquiry, Deposit Request, Withdrawal Inquiry, Withdrawal Request
For example, if you want to place or cancel orders via the Open API, you need to grant Order Placement permission to the API key. If you want to limit the key to only allow trading without deposit/withdrawal capabilities, do not grant Deposit Request and Withdrawal Request permissions.
For details on signing requests, refer to the section on Sending Signed Requests.
curl 'https://api.korbit.co.kr/v2/tickers?symbol=btc_krw'When using the REST API, there are rate limits on the number of requests you can make within a certain timeframe, depending on the type of API. If you exceed these limits, you may encounter a 429 Too Many Requests error. The only consequence of exceeding the rate limit is that you will not receive valid API responses until the limit is reset.
Rate limits are measured based on the IP address for public APIs such as Get Orderbook, while private APIs, like Place Order, are measured based on the member account (not the API key, but the member account). The policies vary by API type as follows:
200 OK
Ratelimit: limit=50, remaining=48, reset=1
Ratelimit-Policy: 50;w=1429 Too Many Requests
Retry-After: 1
Ratelimit-Policy: 30;w=1Korbit Developers provides a FAQ section.
Additionally, Developers offers code examples for sending HMAC-SHA256 or ED25519 signed requests for using the Private API in Go, Node.js, and Python.
Korbit Open API operates on an asynchronous system. Therefore, there may be slight delays in the response data, which is expected and indicates normal operation.
If there is any discrepancy between the Korean API documentation and the English API documentation, the Korean API documentation shall prevail.
With the Open API update, additional fields may be included in the API response. Therefore, when developing a program using the Open API, please consider that new fields might be added to the API response.
The following explains how to sign API requests based on the authentication method (HMAC-SHA256, ED25519) selected during API key creation.
HMAC-SHA256: Korbit generates and provides a secret key, which users must use to sign their API requests using the HMAC-SHA256 method.
ED25519: Users generate their own ED25519 key pair and provide the public key to Korbit during API key creation. Users then sign their API requests using the private key from the key pair.
When making an authenticated API request, you must send a signed request, which includes the signature and timestamp parameters.
The signature parameter is the result of signing a concatenated string of the input variables and the timestamp using either the HMAC-SHA256 or ED25519 method. The timestamp parameter is the current UNIX timestamp in milliseconds. The signature must be included in either the URL query string or the request body.
To ensure time accuracy during signing, the current UNIX timestamp in milliseconds MUST be provided as the timestamp parameter. Therefore, you should first ensure that your computer's current time is synchronized with the standard time. (Note: You can check the time on the Korbit Open API server using the GET /v2/time API.)
Due to potential delays in the network or computer environment, there might be a time difference between when the client signs the request and when the Open API server receives it. In the fast-paced world of cryptocurrency trading, timing is crucial. To prevent unintended request results due to significant time differences, the Korbit Open API can be configured to ignore requests if the time difference exceeds a certain value.
recvWindow: This optional parameter allows users to specify the maximum allowable time difference (in milliseconds) between the signing time and the time the API server receives the request. If not provided, the default value is 5000 milliseconds (5 seconds). The maximum allowable value for this parameter is 60000 milliseconds (60 seconds). For example, if recvWindow=3000 is provided, the API request will be rejected if the server receives it more than 3 seconds after the timestamp.
Lastly, the timestamp cannot be set to a future time. Any request with a timestamp more than 1 second ahead of the API server's time will be rejected.
If a request fails due to an clock error, the server will respond with the EXCEED_TIME_WINDOW error code. In this case, please check the server's time using the /v2/time API.
For stable API operations, please configure the NTP time synchronization feature in your OS.
if (serverTime - timestamp <= recvWindow && timestamp < serverTime + 1000) {
// PROCESS
} else {
// REJECT
}Refer to the attached Node.js example code. Simply replace the API key and secret key with your own to place an order using the code.
If you have generated an API key (system-generated key) for authentication using HMAC-SHA256, first check the secret key provided by Korbit when the API key was created. Also, ensure that the API key has the permissions required to perform the desired functions.
For example, if you want to use the Place Order function, you need to send a POST request to the /v2/orders endpoint of the Korbit Open API. Enter the request parameters according to the order details.
If you want to place a buy order for 1 BTC at a price of 100 million KRW, i.e., a BTC/KRW limit buy order (buy price 100,000,000 and buy quantity 1), you can enter the request parameters as follows:
symbol: btc_krw
side: buy
price: 100000000
qty: 1
Optionally, you can add the timeInForce value to set GTC, IOC, FOK, or Post Only. For a simple limit order, GTC is the default, so you can omit timeInForce or set it to gtc.
For GET and DELETE method requests, enter the request parameters in the URL query string. For POST method requests, enter them in the request body in application/x-www-form-urlencoded format.
Next, as mentioned earlier, you need to enter the current UNIX timestamp (in milliseconds) as the timestamp value. In the example code, recvWindow is set to 5000, but you can omit recvWindow if you want (it defaults to 5000). Note that the order of the request parameters, including the timestamp, does not matter.
To sign the message, concatenate all request parameters into a single string, and then generate the HMAC-SHA256 signature using the secret key.
For example, create a string like symbol=btc_krw&side=buy&price=100000000&qty=1&orderType=buy×tamp=1719232467910, and sign it using the secret key. Refer to the API documentation, Developers examples, or resources like internet searches or ChatGPT for HMAC-SHA256 signature generation methods in different programming languages.
If request parameters exist in both the URL query string and the HTTP request body, concatenate them as-is. For example, if timestamp=1719232467910 is in the query string and symbol=btc_krw is in the request body, the string to sign becomes timestamp=1719232467910symbol=btc_krw (note: no & between query string and request body).
Once the signature is generated, add it to the request parameters as signature.
It's time to send the API request. For private API requests like placing an order, send the API key in the HTTP request header as X-KAPI-KEY along with the signed message. If you are not using a library that automatically handles HTTP requests, also include Content-Type: application/x-www-form-urlencoded.
If the request is successful, you will receive a response indicating that the order has been placed in JSON format. Note that even if the request is successful, the order will not be placed if you do not have sufficient KRW balance for the cryptocurrency purchase.
// Node.js Example

.then((data) => console.log("Cancel Response:", data))
.catch((err) => console.error("Cancel Error:", err));Refer to the attached Node.js example code. Simply replace the API key and private key with your own to place an order using the code.
If you have generated an API key for authentication using the ED25519 method (user-generated key), first check the private key you provided to Korbit when creating the key. Also, ensure that the API key has the permissions required to perform the desired functions.
For example, if you want to use the Place Order function, you need to send a POST request to the /v2/orders endpoint of the Korbit Open API. Enter the request parameters according to the order details.
If you want to place a buy order for 1 BTC at a price of 100 million KRW, i.e., a BTC/KRW limit buy order (buy price 100,000,000 and buy quantity 1), you can enter the request parameters as follows:
symbol: btc_krw
side: buy
price: 100000000
qty: 1
Optionally, you can add the timeInForce value to set GTC, IOC, FOK, or Post Only. For a simple limit order, GTC is the default, so you can omit timeInForce or set it to gtc.
For GET and DELETE method requests, enter the request parameters in the URL query string. For POST method requests, enter them in the request body in application/x-www-form-urlencoded format.
Next, as mentioned earlier, you need to enter the current UNIX timestamp (in milliseconds) as the timestamp value. In the example code, recvWindow is set to 5000, but you can omit recvWindow if you want (it defaults to 5000). Note that the order of the request parameters, including the timestamp, does not matter.
To sign the message, concatenate all request parameters into a single string, and then generate the ED25519 signature using the private key.
For example, create a string like symbol=btc_krw&side=buy&price=100000000&qty=1&orderType=buy×tamp=1719232467910, and sign it using the private key. Refer to the API documentation, Developers examples, or resources like internet searches or ChatGPT for ED25519 signature generation methods in different programming languages.
The generated ED25519 signature must be encoded in Base64 format before being sent to Korbit.
If request parameters exist in both the URL query string and the HTTP request body, concatenate them as-is. For example, if timestamp=1719232467910 is in the query string and symbol=btc_krw is in the request body, the string to sign becomes timestamp=1719232467910symbol=btc_krw (note: no & between query string and request body).
Once the signature is generated, add it to the request parameters as signature.
It's time to send the API request. For private API requests like placing an order, send the API key in the HTTP request header as X-KAPI-KEY along with the signed message. If you are not using a library that automatically handles HTTP requests, also include Content-Type: application/x-www-form-urlencoded.
When using an ED25519 API key, ensure that the Base64-encoded signature is URL-encoded when sent to Korbit. Use a utility like URLSearchParams in Node.js to handle the string conversion automatically or ensure the library used for sending HTTP requests properly URL-encodes the data. If handling HTTP requests manually, as with cURL, use the --data-urlencode option.
If the request is successful, you will receive a response indicating that the order has been placed in JSON format. Note that even if the request is successful, the order will not be placed if you do not have sufficient KRW balance for the cryptocurrency purchase.

}The WebSocket API is a WebSocket connection interface designed for bidirectional communication between the Korbit server and user clients. Using the WebSocket API allows you to receive real-time information from the Korbit cryptocurrency exchange at the fastest possible speed.
With the REST API, users must send an HTTP request to receive a response and retrieve information. However, with the WebSocket API, a persistent, bidirectional connection is maintained between the Korbit server and user client. As a result, when events such as price changes or order executions occur, information is continuously delivered from the Korbit server to the user client in real-time. Therefore, if you aim to receive real-time information on prices, orders, and trades quickly and conveniently, we recommend using the WebSocket API over the REST API.
Data provided by the WebSocket API is classified into Public and Private types, depending on whether it is public information or specific to individual users. Public type data can be received without any authentication. However, to receive Private type data, authentication with Korbit Open API keys is required when establishing the WebSocket connection.
For Public type data, sending a subscription request via WebSocket immediately provides the latest data at the time of the request as snapshot data. (Snapshot data is not real-time.) All non-snapshot data is real-time.
There are separate WebSocket endpoints for each of the types, public and private. Please connect to the correct endpoint for the type you want to subscribe.
WebSocket Endpoint URL: wss://ws-api.korbit.co.kr/v2/public
ticker : Provides snapshots and real-time current prices for a specified trading pair.orderbook : Provides snapshots and real-time order book data for a specified trading pair.trade : Provides snapshots and real-time trade history for a specified trading pair.WebSocket Endpoint URL: wss://ws-api.korbit.co.kr/v2/private
myOrder : Provides real-time status updates on your orders.myTrade : Provides real-time execution updates on your trades.myAsset : Provides real-time updates on your assets.We've launched a new WebSocket API in Feburary 2025. Former WebSocket API(/v2/ws) will continue to operate until May 31, 2025. Please migrate to the new WebSocket API(/v2/public and /v2/private) before May 31.
wss://ws-api.korbit.co.kr/v2/publicwss://ws-api.korbit.co.kr/v2/privatePublic type data (Ticker, Orderbook, Trade) can be received simply by connecting to the WebSocket and sending a subscription message, without any authentication. However, to receive Private type data (My Order, My Trade), authentication using Korbit Open API keys is required upon establishing the WebSocket connection.
For authentication, as with the REST API, you need to send a request with an X-KAPI-KEY header and a signature generated using either HMAC-SHA256 or ED25519 during the WebSocket connection. Specifically, include the X-KAPI-KEY in the request header, and add timestamp and signature information to the URL query string.
Please refer to the Sign API Requests section and the attached example code for more details.
// Node.js, npm i ws
import crypto from "crypto";
import WebSocket from "ws";
const apiKey = "XyAZ_apaUv9pg4ZyGzNHTxabfIDrWIRpPBgk5-olIuM"; // API Key
const apiSecret = "ZwKS2evdxj9j3Neir2s0UHAmpNFfo4a0iHawEElGCBs"; // HMAC-SHA256 Secret Key
const wsUrl = "wss://ws-api.korbit.co.kr/v2/private"; // Private type endpoint URL
// HMAC-SHA256 Signature
const createHmacSignature = (query) => {
return crypto.createHmac("sha256", apiSecret).update(query, "utf-8").digest("hex");
};
const timestamp = Date.now(); // Timestamp (ms)
const params = new URLSearchParams({
timestamp: timestamp,
});
const signature = createHmacSignature(params.toString());
// Add Signature to params
params.append("signature", signature);
// Add API Key to the header, Open a WebSocket connection
const ws = new WebSocket(`${wsUrl}?${params.toString()}`, [], {
headers: {
"X-KAPI-KEY": apiKey,
}
});
ws.on("open", () => {
console.log("connected!");
// Send messages to subscribe
ws.send(`[{"method":"subscribe","type":"myOrder","symbols":["btc_krw","eth_krw"]},{"method":"subscribe","type":"myTrade","symbols":["btc_krw","eth_krw"]}]`);
});
ws.on("error", (error) => {
console.error('websocket error', error);
});
ws.on("message", (data) => {
const message = JSON.parse(data);
console.log(message);
});
ws.on("close", (code, message) => {
console.log("connection closed!", code, message);
});
ws.on("unexpected-response", async (request, response) => {
let data = '';
for await (const chunk of response) {
data += chunk;
}
console.log("websocket connect fail", response.statusCode, data);
if (response.headers["content-type"]?.startsWith("application/json")) {
const errorJson = JSON.parse(data)
const msg = errorJson.error?.message
// e.g.) EXCEED_TIME_WINDOW, KEY_NOT_FOUND, ...
console.log("auth error", msg)
}
});After the WebSocket connection is established, you must send a request indicating which type of data you wish to subscribe to. In the WebSocket API, subscription request messages are sent in JSON format, with method, type, and symbols specified accordingly.
Since multiple messages can be included at once, even when sending a single request message, it must be enclosed in square brackets []. (Please note that case sensitivity applies.)

First, snapshot data is received, followed by a continuous stream of real-time data. If you want to receive information for multiple trading pairs, enclose the pairs in square brackets [] and separate them with commas ,, as shown in the example above.
To subscribe, set method to subscribe; to stop receiving a specific type of data, set method to unsubscribe to cancel the subscription.
Refer below for example subscription request and response messages for each type.
There are two kinds of messages sent from the server.
Messages without status field are real-time data, which can be subscribed using the subscribe request message.
{"type": "type of the message", ...}
{"type": "ticker", "timestamp": 1700000027754, "symbol": "btc_krw", "data": {...}}Messages with status field are control messages, which are sent by the server to notify results or errors.
{"status": "success", "requestId": 1}
{"status": "fail", "requestId": 2, "code": "..."}
{"status": "error", "message": "..."}By default, no responses will be sent when subscribe/unsubscribe requests succeed, and only failure responses are sent.
In case you want to check the result for each requests, you can set a unique integer to the requestId field of the request message, and a response message with the same requestId will always be sent, even if it succeedes.
