Chainlink Node API Reference

Suggest Edits

The Chainlink Node API reference provides information on how to interact directly with a Chainlink node. If you are creating services which need direct communication with a Chainlink node, this information will be helpful for you. If you are wanting to connect an external resource (API) to a smart contract using Chainlink, please see the the Developers section of external adapters.

Most endpoints of the Chainlink node require session authentication. You will need to POST to /session to create a cookie to be used for subsequent requests.
