contract which use AggregatorV3Interface interface.
I use this data-feeds contract in this link (https://docs.chain.link/docs/matic-addresses/)
But I wonder about it is free from gas fee.
I think it is not free, but I can get the price data for free.
Anyone help ?
You could get that data for free because some nodes are sponsoring these feeds.
Thanks, You mean some nodes just provide their price data to user for free??? Can you explain about sponsoring more details??
