How often do i need to fetch exchange info when fetching Filters for coin pair ?

API Spot/Margin API

https://api.binance.com/api/v3/exchangeInfo?symbol=${symbol}

In order to get the Filters for a coin pair, I hit this endpoint, for every coin pair I need to operate on, which is expensive in terms of time.

Can I just fetch info for all pairs and persist, then operate based on the persisted info (i.e how often does the data change and how often do I need to fetch this info ?)

Hi. Please refer to this document. https://binance-docs.github.io/apidocs/spot/en/#exchange-information
You don’t have to attach the parameter if you want the whole data.
