The api https://www.binance.com/exchange/public/product seems to work again.
could you please verify?

this is not a proper URL to get symbols information, please only work on endpoints from the API. This endpoint can be helpful to find all symbol info. https://binance-docs.github.io/apidocs/spot/en/#exchange-information

actually you shouldn’t use that url at all, it’s not a API endpoint. “GET /api/v3/ping” this can be used for testing connectivity.

That's what one of the guys from the API telegram stated when I showed the link was unsuccessful.

does that help?

unfortunately that call doesn't contains all the info than the "product" call.
this is a complex fix....
