API Rate Limit Illustration for USDT-margined Contracts:

The API rate limits of Coin-margined futures, coin-margined swaps, and USDT-margined contracts are separate. USDT-margined contracts include USDT-margined futures and USDT-margined swaps, therefore, both of them share the mutual API rate limit.

Please note that there are rate limits for both public interfaces and private interfaces. Details are as below:

  • For common users, the rate limit of private interfaces requiring API key is at most 144 times every 3 seconds for each UID (Trading Interface: at most 72 times every 3 seconds. Query Interface: at most 72 times every 3 seconds) (this rate limit is shared by all the requests from all the private interfaces of USDT-margined contracts for a certain user). API Interface List
  • For non-marketing public interfaces used to get information such as index, price limit, settlement, delivery, open positions, etc, the rate limit is at most 240 times every 3 seconds for each IP (this rate limit is shared by all the requests from non-marketing public interfaces of USDT-margined contracts for a certain IP, like above).
  • For the public interfaces to get market data such as Get Kline data, Get Market Data Overview, Get Contract Information, Get Market In-depth Data, Get Premium Index Kline, Get Real-time Forecast Capital Rate Kline, Get Basis Data, Get the Last Trade of a Contract and so on:

(1)For restful interfaces, the rate limit for all derivatives (coin-margined futures, coin-margined swaps, and USDT-margined contracts) is at most 800 times/1s for an IP.
(2)For websocket interfaces, the rate limit for a“req” request is 50 times at once. No limit for a“sub” request as the data will be pushed by the Sever voluntarily.

  • For private order push interfaces of WebSocket (requiring API Key Verification):
    Each UID can make at most 30 WS connections for private order push at the same time. For each account, contracts of the same underlying asset (including contracts with different expiration dates) only need to subscribe a WS order push, e.g. users only need to create one WS order push connection for BTC/USDT Contracts. Please note that the rate limit of WS order push is separated from that of RESTFUL private interfaces, without mutual effect.
  • There will have rate limit info in the "header" returned by the trading and query interfaces. E.g., you will get the total query rate limit via the "ratelimit-limit" and get the remaining query rate limit via the "ratelimit-remaining" in the "header" returned by the "Query the Order Info" interface (URL: /linear-swap-api/v1/swap_account_info). And you will get the total trading rate limit via the "ratelimit-limit") and get the remaining trading rate limit via the "ratelimit-remaining" in the "header" returned by the "Place an Order" interface (URL: /linear-swap-api/v1/swap_order). API Interface List
  • Rate limit info will be added to the returned data of all API interfaces.

The following fields will be included in the "header" returned by the "response" via all API interfaces:

       ratelimit-limit: the max request times for a round, unit: times
       ratelimit-interval: reset interval (to reset the request times), unit: ms
       ratelimit-remaining: the remaining available request times for this round, unit: times
       ratelimit-reset: reset time (when the max request times are reached), unit: ms

When API limitation on Order Cancellation Ratio is triggered, the following field will be included in the "header" returned by the "response" via API interfaces:

"recovery-time": recovery timestamp (unit: ms) meaning the end time of the prohibition, or the access retrieval timestamp;

If you are not in the prohibition period, the field is not included in the returned "header";

  • The rate limit for a "Place a Trigger Order" request, a "Cancel a Trigger Order" request, and a "Cance all Trigger Orders" request is 5 times/1s for a UID.
