Hello Chainlink, I have a question about getting price from

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.
