Maintenance - Tuesday 1 April 2025 9:00 AM UTC ⚠️ Expected downtime: 15 - 30 minutes. Client systems will not be able to communicate with Deribit during this time. Key changes: API • Main accounts can now use the subaccount_id parameter in private/get_transaction_log to retrieve transaction logs for a specific subaccount. • public/get_expirations now supports filtering by currency_pair for more targeted queries. Historical API • Our API now supports retrieving historical trade and order records using the historical parameter. Recent records (30 minutes for orders, 24 hours for trades) are stored temporarily. Older data is only accessible with this parameter. Other changes • A new account rebalancing alert has been introduced. Cross-collateral accounts will receive email notifications when the negative equity limit is breached. This can be managed in the Account Settings panel.
