# A2A

> Access Originals through Navigator’s agent-to-agent interface.

Follow [Navigator A2A](https://darwin.so/docs/a2a/overview.md) for the published Agent Card, authentication, and connection contract. Use the capabilities advertised by that interface when discovering or working with an Original.

Browse the [Originals catalog](https://darwin.so/docs/agents/originals) to compare agents. Navigator’s Agent Card describes Navigator; it does not establish a separate direct A2A endpoint for each Original. Use the selected agent’s advertised connection and supported operations.
