Important Update: Upgrade Plan for Spot High-Frequency Accounts

Dear KuCoin Spot API Users,
Since the launch of the high-frequency Spot account last year, the stability of the Spot API has significantly improved, and latency has been greatly reduced. However, currently, two systems coexist, and customers using the low-frequency system still experience high latency and other issues. Therefore, from July to September, we will be merging and migrating the existing low-frequency and high-frequency systems. The overall process is as follows:
Release Schedule:
This update will be rolled out in batches based on user UID, and only affected customers will be impacted:
First batch update: 2024-07-04 2:00-5:00（UTC）
Second batch update: 2024-07-08 1:00 - 2024-07-10 10:00（UTC）
Impact During Release:

This release will only affect low-frequency accounts, with high-frequency accounts remaining unaffected (migration of the first batch of low-frequency accounts). During the migration process, there may be a brief few-second window where order placement, cancellation, and account query operations may be unavailable. Additionally, Spot orders on low-frequency accounts may be canceled by the system (affecting APP/WEB/API).
Post-Release Impact:

WEB/APP Transfer Records Query
All instances of trade_hf on the page will be changed to trade. This means that if there were previous records of transfers from trade to trade_hf, they will now appear as trade<-->trade. For original records, please contact customer support to export them manually.
Get Account Details:

Related Endpoint:

• Get Account Details - Spot/Margin/Spot High-Frequency: GET /api/v1/accounts/{accountId}

Before Migration:

• Both high-frequency and low-frequency users can query the asset details of the respective business lines using accountId.

After Migration:

• Low-Frequency Users: The accountId for the ‘spot’ account will change. Use the Get Account List endpoint `GET /api/v1/accounts` to obtain the new accountId for the ‘spot’ account.
• High-Frequency Users: No code modification is required.

Summary:
For users who already have a high-frequency account and currently only use the high-frequency account, no code modification is needed for this update. For users who have not yet opened a high-frequency account, use the Get Account List endpoint `GET /api/v1/accounts` to get the new accountId.
