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, 02:00-05:00 (UTC)

Second batch update: 2024-07-10, 02:00-05:00 (UTC)

Impact During Release

This release will only affect low-frequency accounts, with high-frequency accounts remaining unaffected. 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.

1. 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.
2. 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.
