Will there be free data feeds?

Data providers can choose to offer their data feeds to subscribers at no cost, however the data provider will still need to pay any applicable Ethereum network fees required for smart contract operation.

If the data feed does not require any interaction with the blockchain (e.g. raw data, not oraclized) then there are no fees for subscriber or provider.

The Zap Store may subsidize certain free data feeds, such as cryptocurrency exchange rate data feeds.
