5. Market Maker Endpoints

The following API endpoints are only available to market makers. The Github link for each query will provide access to the corresponding Endpoints Weights, Parameters, and Responses.

Query	Description	Endpoint and Details
Option Margin Account Information (USER_DATA)	Get current account information	GET /eapi/v1/marginAccount (HMAC SHA256)
Set Market Maker Protection Config (TRADE)	Set config for MMP. Market Maker Protection (MMP) is a set of protection mechanisms for option market makers. This mechanism can prevent mass trading in a short period of time. Once a market maker's account breaches the threshold, MMP will be triggered. All current MMP orders will be canceled, and all new MMP orders will be rejected. Market makers can use this gap to re-evaluate the market and modify order prices.	POST /eapi/v1/mmpSet (HMAC SHA256)
Get Market Maker Protection Config (TRADE)	Get config for MMP	Get /eapi/v1/mmp (HMAC SHA256)
Reset Market Maker Protection Config (TRADE)	Reset MMP and start MMP orders again	POST /eapi/v1/mmpReset (HMAC SHA256)
Set Auto-Cancel All Open Orders (Kill-Switch) Config (TRADE)	This endpoint sets the parameters of the auto-cancel feature. If no heartbeat message is sent, it will cancel all open orders (MMP and non-MMP orders) of the underlying symbol at the end of the specified countdown period. After the countdown period, all open orders will be canceled. New orders will be rejected with the error code -2010 until either a heartbeat message is sent or the auto-cancel feature is turned off by setting the countdownTime to 0.	POST /eapi/v1/countdownCancelAll (HMAC SHA256)
Get Auto-Cancel All Open Orders (Kill-Switch) Config (TRADE)	This endpoint returns the auto-cancel parameters for each underlying symbol. Please note that only active auto-cancel parameters will be returned. If the countdownTime is set to 0 (i.e., countdownTime has been turned off), the response won’t return the underlying symbol, and the corresponding countdownTime parameter won’t be returned in the response.	GET /eapi/v1/countdownCancelAll (HMAC SHA256)
Auto-Cancel All Open Orders (Kill-Switch) Heartbeat (TRADE)	This endpoint resets the time from which the countdown will begin to the time this message is received. It should be called repeatedly as heartbeats. Multiple heartbeats can be updated at once by specifying the underlying symbols as a list (except BTCUSDT and ETHUSDT) in the underlying parameter.	POST /eapi/v1/countdownCancelAllHeartBeat (HMAC SHA256)
