Changelog

2026-04-29

• Signature documentation corrected: the PreHash formula is now stated explicitly as timestamp + method + requestPath + (?queryString)? + body, and requestPath excludes the gateway prefixes /spot/open and /futures/open — sign with /sapi/v1/... or /fapi/v1/... only. The most common integration failures are documented in the FAQ checklist.
• Spot /sapi and futures /fapi rewritten to match the actual backend controllers (Spot trading, Futures trading). Added or corrected several fields (symbols.limitPriceMin/limitVolumeMin/marketBuyMin/marketSellMin, futures kline interval accepts 1h, myTrades.limit is capped at 100, etc.).
• Added futures endpoints: all_ticker, get_all_indexPrice, public_all_index_tag_price, openOrdersCount, tradesRecord, adlRecord, liquidationList, profitLossOrder, trigger_order_list, cancel_trigger_order, positions, capital, edit_lever, edit_user_position_model.
• Added documentation for the RSA-signed funds-transfer endpoints futures_transfer / futures_balance (these do not reuse X-CH-SIGN).
• Added end-to-end signing examples for both GET and POST in General information (PreHash + openssl + curl).

• New release online

To optimize system architecture and improve service stability, the platform will migrate the Open API routing domain. The legacy Open API domain api.bitbaby.com will move to openapi.bitbaby.com. All Open API users should update endpoint hostnames as soon as possible.

Important: This migration only changes the subdomain; existing API paths stay the same, for example:

• Before: https://api.bitbaby.com/spot/open/
• After: https://openapi.bitbaby.com/spot/open/

Paths, parameters, and calling conventions remain unchanged.

Migration schedule:

• New Open API hostname: openapi.bitbaby.com
• Legacy domain sunset: March 20, 2026, 18:00 (UTC+8)

After this time, Open API routes under api.bitbaby.com will stop serving. If you do not migrate in time, API calls may fail or orders may not be placed.
