eAPI over SSH provides programmatic access to Arista EOS Command API using SSH as the transport protocol, offering an alternative to HTTP/HTTPS-based eAPI. This feature enables network automation tools and scripts to execute CLI commands and retrieve structured output via JSON-RPC 2.0 over an SSH connection.

The feature uses the standard SSH subsystem mechanism, allowing clients to invoke the "eapi" subsystem after SSH authentication. Commands and responses use the same JSON-RPC 2.0 format as HTTP-based eAPI, ensuring compatibility with existing eAPI client libraries and scripts with minimal modifications.
