Suggest Edits

To learn how to implement these feeds, see the Ethereum Examples for Consuming Data Feeds.

For LINK token and Faucet details, see the LINK Token Contracts page.

Notes:

  • Off-chain equity and ETF assets are traded only during standard market hours from 9:30AM to 4:00PM EDT Monday through Friday.
  • Assets on the Forex (Foreign Exchange) markets are traded only from 5PM EDT on Sunday through 4PM EDT on Friday.

Using these feeds outside of those windows is not recommended.

Data feeds reside in the following categories:

  • 🟢 Verified Feeds: Feeds that follow a standardized data feeds workflow
  • 🟡 Monitored Feeds: Feeds under review by the Chainlink Labs team to support the stability of the broader ecosystem
  • 🔵 Custom Feeds: Feeds built to serve a specific use case and might not be suitable for general use
  • âš« Specialized Feeds: Purpose-built feeds that might rely on contracts maintained by external entities and require in-depth understanding of composition methodology before use

See the Selecting Quality Data Feeds page for complete details about each category.

Please be careful with the feeds used by your smart contracts. The feeds listed in our official documentation have been reviewed; feeds built for custom deployments by other community members might have additional risks. Please do close diligence on your feeds before implementing them in your contracts. Learn more about making responsible data quality decisions.
