How to get 'premium index' via API?

[LKresta]

Hello there,

I checked the documentation and samples but could not find any info on how to obtain premium index values (https://www.gate.io/futures_info_new/futures/btc/BTC_USD#indexinfo, 'premium index'). Is there any way in API to retrieve this value over time/subscribe to updates/...?

Thanks, L.

I found something like /api/v4/futures/usdt/premium_index?contract=BTC_USDT&from=1667271733&to=1667314993&interval=5m, is it safe to use?

Yes, it's safe to use. We'll also update the API details to our public documents.
