+
+Query risk limit tiers
+
+When the 'contract' parameter is not passed, the default is to query the risk limits for the top 100 markets. 'Limit' and 'offset' correspond to pagination queries at the market level, not to the length of the returned array. This only takes effect when the contract parameter is empty.

-Borrow or repay
-
-When borrowing, it is essential to ensure that the borrowed amount is not below the minimum borrowing threshold for the specific cryptocurrency and does not exceed the maximum borrowing limit set by the platform and the user.  The interest on the loan will be automatically deducted from the account at regular intervals. It is the user's responsibility to manage the repayment of the borrowed amount.  For repayment, the option to repay the entire borrowed amount is available by setting the parameter `repaid_all=true`

+Create lending or redemption
 
-`Lending`:  The minimum interest rate is required in lending. The lending result is updated hourly and the interest profit is paid on the next hour. A high interest rate might lead to unsuccessful lending and no profit will be gained for that hour. If the funds are redeemed before the hourly settlement, no interest can be obtained for that hour. About priority: the orders created or amended first under the same interest rate will be lent out first  `Redemption`:  Funds that failed to be lent can be redeemed immediately.  For the successfully lent funds, enjoy the hourly income, and the redemption will arrive at the next hour  `Note`:  Two minutes before and after the hour is the settlement time, lending and redemption are prohibited. 
+Lending: When lending, a minimum lending rate must be set. After successful lending is determined on an hourly basis, earnings will be calculated based on the determined rate.  Earnings for each hour will be settled at the top of the hour. If lending fails due to an excessively high interest rate, no interest will be earned for that hour.  If funds are redeemed before the hourly for that hour.  Priority: Under the same interest rate, wealth management products created or modified earlier will be prioritized for lending.  Redemption: For funds that failed to be lent, redemption will be credited immediately. For funds successfully lent, they are entitled to the earnings for that hour, and redemption will be credited in the next hourly interval.  Note: The two minutes before and after the hourly mark are the settlement period, during which lending and redemption are prohibited.

-- Creating futures orders requires `size`, which is number of contracts instead of currency amount. You can use `quanto_multiplier` in contract detail response to know how much currency 1 size contract represents - Zero-filled order cannot be retrieved 10 minutes after order cancellation. You will get a 404 not found for such orders - Set `reduce_only` to `true` can keep the position from changing side when reducing position size - In single position mode, to close a position, you need to set `size` to 0 and `close` to `true` - In dual position mode, to close one side position, you need to set `auto_size` side, `reduce_only` to true and `size` to 0 - Set `stp_act` to decide the strategy of self-trade prevention. For detailed usage, refer to the `stp_act` parameter in request body 
+- When placing an order, the number of contracts is specified `size`, not the number of coins. The number of coins corresponding to each contract is returned in the contract details interface `quanto_multiplier` - 0 The order that was completed cannot be obtained after 10 minutes of withdrawal, and the order will be mentioned that the order does not exist - Setting `reduce_only` to `true` can prevent the position from being penetrated when reducing the position - In single-position mode, if you need to close the position, you need to set `size` to 0 and `close` to `true` - In dual warehouse mode,   - Reduce position: reduce_only=true, size is a positive number that indicates short position, negative number that indicates long position  - Add number that indicates adding long positions, and negative numbers indicate adding short positions  - Close position: size=0, set the direction of closing position according to auto_size, and set `reduce_only` to true  at the same time - reduce_only: Make sure to only perform position reduction operations to prevent increased positions - Set `stp_act` to determine the use of a strategy that restricts user transactions. For detailed usage, refer to the body parameter `stp_act`

 Countdown cancel orders
 
-When the timeout set by the user is reached, if there is no cancel or set a new countdown, the related pending orders will be automatically cancelled.  This endpoint can be called repeatedly to set a new countdown or cancel the countdown. For example, call this endpoint at 30s intervals, each countdown`timeout` is set to 30s. If this endpoint is not called again within 30 seconds, all pending orders on the specified `market` will be automatically cancelled, if no `market` is specified, all market pending orders will be cancelled. If the `timeout` is set to 0 within 30 seconds, the countdown timer will expire and the cacnel function will be cancelled.
+Heartbeat detection for contract orders: When the user-set `timeout` time is reached, if neither the existing countdown is canceled nor a new countdown is set, the relevant contract orders will be automatically canceled. This API can be called repeatedly to or cancel the countdown. Usage example: Repeatedly call this API at 30-second intervals, setting the `timeout` to 30 (seconds) each time. If this API is not called again within 30 seconds, all open orders on your specified `market` will be automatically canceled. If the `timeout` is set to 0 within 30 seconds, the countdown timer will terminate, and the automatic order cancellation function will be disabled.

If this interface is not called again within 30 seconds, all pending orders on the `underlying` `contract` you specified will be automatically cancelled. If `underlying` `contract` is not specified, user will be automatically cancelled  If `timeout` is set to 0 within 30 seconds, the countdown timer will expire and the automatic order cancellation function will be cancelled.

-List all currencies' details
+Query all currency information
 
-Currency has two forms:  1. Only currency name, e.g., BTC, USDT 2. `<currency>_<chain>`, e.g., `HT_ETH`  The latter one occurs when one currency has multiple chains. Currency detail contains a `chain` field whatever the form is. To retrieve all chains of one currency, you can use use all the details which has the name of the currency or name starting with `<currency>_`.
+When a currency corresponds to multiple chains, you can query the information of multiple chains through the `chains` field, such as the charging and recharge status, identification, etc. of the chain

-支持现货、杠杆、全仓杠杆下单。通过 `account` 字段来使用不同的账户，默认为 `spot` ，即使用现货账户下单。  使用杠杆账户交易，即 `account` 设置为 `margin` 的时候，可以设置 `auto_borrow` 为 `true`， 在账户余额不足的情况，由系统自动执行 `POST /margin/loans` 借入不足部分。 杠杆下单成交之后的获取到的资产是否自动用于归还逐仓杠杆账户的借入单，取决于用户逐仓杠杆**账户**的自动还款设置， 该账户自动还款设置可以通过 `/margin/auto_repay` 来查询和设置。  使用全仓杠杆账户交易，即 `account` 设置为 `cross_margin` 的时候，同样可以启用 `auto_borrow` 来实现自动借入不足部分，但是与逐仓杠杆账户不同的是，全仓杠杆账户的委托是否自动还款取决于下单时的 `auto_repay` 设置，该设置只对当前委托生效，即只有该委托成交之后获取到的资产会用来还款全仓杠杆账户的借入单。 全仓杠杆账户下单目前支持同时开启 `auto_borrow` 和 `auto_repay`。  自动还款会在订单结束时触发，即 `status` 为 `cancelled` 或者 `closed` 。  **委托状态**  挂单中的委托状态是 `open` ，在数量全部成交之前保持为 `open` 。如果被全部吃掉，则订单结束，状态变成 `closed` 。 假如全部成交之前，订单被撤销，不管是否有部分成交，状态都会变为 `cancelled`  **冰山委托**  `iceberg` 用来设置冰山委托显示的数量，如果需要完全隐藏，设置为 `-1` 。注意隐藏部分成交时按照 taker 的手续费率收取。  **限制用户自成交**  设置 `stp_act` 来决定使用限制用户自成交的策略
+Supports spot, margin, leverage, and cross-margin leverage orders. Use different accounts through the `account` field. Default is `spot`, which means using the spot account to place orders. If the user has a `unified` account, the default is to place orders with the unified account.  When using leveraged account trading (i.e., when `account` is set to `margin`), you can set `auto_borrow` to `true`. In case of insufficient account balance, the system will automatically execute `POST /margin/uni/loans` to borrow the insufficient amount. Whether assets obtained after leveraged order execution are automatically used to repay borrowing orders of the isolated margin account depends on the automatic repayment settings of the user's isolated margin account. Account automatic repayment settings can be queried and set through `/margin/auto_repay`.  When using unified account trading (i.e., when `account` is set to `unified`), `auto_borrow` can also be enabled to realize automatic borrowing of insufficient amounts. However, unlike the isolated margin account, whether unified account orders are automatically repaid depends on the `auto_repay` setting when placing the order. This setting only applies to the current order, meaning only assets obtained after order execution will be used to repay borrowing orders of the cross-margin account. Unified account ordering currently supports enabling both `auto_borrow` and `auto_repay` simultaneously.  Auto repayment will be triggered when the order ends, i.e., when `status` is `cancelled` or `closed`.  **Order Status**  The order status in pending orders is `open`, which remains `open` until all quantity is filled. If fully filled, the order ends and status becomes `closed`. If the order is cancelled before all transactions are completed, regardless of partial fills, the status will become `cancelled`.  **Iceberg Orders**  `iceberg` is used to set the displayed quantity of iceberg orders and does not support complete hiding. Note that hidden portions are charged according to the taker's fee rate.  **Self-Trade Prevention**  Set `stp_act` to determine the self-trade prevention strategy to use

If this endpoint is not called again within 30 seconds, all pending orders on the specified `market` will be automatically cancelled, if no `market` is specified, all market pending orders will be cancelled.

+Spot order heartbeat detection. If there is no \"cancel existing countdown\" or \"set new countdown\" when the user-set `timeout` time is reached, the related `spot pending orders` will be automatically cancelled. This interface can be called repeatedly to set a new countdown or cancel the countdown. Usage example: Repeat this interface at 30s intervals, setting the countdown `timeout` to `30 (seconds)` each time. If this interface is not called again within 30 seconds, all pending orders on the `market` you specified will be automatically cancelled. If no `market` is specified, all market cancelled.

+# **create_unified_loan**
+> UnifiedLoanResult create_unified_loan(unified_loan)
+
+Borrow or repay
+
+When borrowing, ensure the borrowed amount is not below the minimum borrowing threshold for the specific cryptocurrency and does not exceed the maximum borrowing limit set by the platform and user.  Loan interest will be automatically deducted from the account at regular intervals. Users are responsible for managing repayment of borrowed amounts.  For repayment, use `repaid_all=true` to repay all available amounts
