Feature Request: Bulk Open Interest Endpoint for All Symbols
Background
The current Open Interest API (/openInterest) requires a separate request for each symbol:
GET /fapi/v1/openInterest?symbol=BTCUSDT
For portfolios that track many futures contracts, this leads to high request counts , increased latency and higher API usage costs.
Would Binance consider adding a bulk open interest endpoint that returns the open interest for all symbols (or a selectable subset) in a single HTTP request?
