[Additional notes on Exchange API]

• Even in the case of requests within this standard, if multiple Open API Keys are used on one account, the number of requests may be limited to provide stable service for the entire Upbit.
• The above number of requests may not be temporarily guaranteed depending on the conditions for the server and services.
• Check the remaining number of available requests by referring to the method below which describes how to check the remaining number of requests.
• (Update) The order request API and non-order request API request limit are counted separately.

QUOTATION API

1. Limit the number of Websocket connection requests

   1. Upon requesting a WebSocket connection with authentication information (jwt token) in the header it is measured on an account basis. (*To receive Public data, no special authentication is required, but authentication is required to receive Private data.)

      • WebSocket connection request: 5 times/sec
      • WebSocket Data Request*: 5 times/sec, 100 times/min
        *Data requested such as My Trade (execution data) upon connection.

   2. Upon requesting a WebSocket connection without authentication information, it is measured on an IP basis.

      • WebSocket connection request: 5 times/sec
      • WebSocket Data Request*: 5 times/sec, 100 times/min
        *Data requested such as Current Price/ Execution/ Order Book information for a specific market

2. REST API limit is measured on an IP basis.

• 10 times/sec (Market, Candle, Execution, Ticker, Order Book has its own limit)
• 
  

[Additional notes on Quotation API]

• To ensure consistent service in the future, the amount of API requests may be modified. We will notify you through a separate notice to keep you informed
• The time condition that applies to the limit on the number of requests is based on the time of the first request and is initiated after a certain period of time. (Failed requests are not included in the number of requests.)
• If you need multiple REST API requests, please receive them through WebSocket.

The Upbit Developer Center is committed to providing more stable and advanced services in the future.

If there are any changes to the limit on the number of requests in the future, we will make sure to notify you through a separate notice.

[Check the Remaining Exchange API Requests]

Upbit Open API service puts a limit on the number of requests per second for a seamless usage environment. When you call API, the number of remaining requests can be seen through the Remaining-Req response header.

Remaining-Req: group=default; min=1799; sec=29

If you received a response header in the format above, this means you are allowed to make 29 requests that second and 1,799 requests during the remaining 1 minute for the default group.

🚧

If there are requests that exceed the allotted time, a 429 Too Many Requestserror may occur. However, no additional penalty will be imposed.
