Data Provider Nodes

Introduction to Data Provider Nodes

Chainlink has facilitated the launch of several new oracle data services that allow dApps to access rich data from external data sources. These oracles expand the types of data available on Chainlink and include data and use cases that do not fit into the traditional Chainlink feed model.

Data provider nodes allow customizable, on-demand API calls and the ability to deliver different data points on each request. This enables use cases where each requestor requires a different piece of data.

Using single provider data nodes on production networks

When you run a production application, be aware of the risks and implications of using a single data source for production networks. Any error or omission in the provider's data might negatively impact your application and its users.
