External Adapters

External adapters are how Chainlink enables easy integration of custom computations and specialized APIs. External adapters are services which the core of the Chainlink node communicates via its API with a simple JSON specification.

Information on external adapters is broken up into three main categories: contract creators, developers, and node operators.

  • Contract Creators will need to know how to specify an external adapter in their request for external data.
  • Developers will need to know how to implement an external adapter for an API.
  • Node Operators will need to know how to add an external adapter to their node so that they can provide specialized services to smart contracts.
