LocalAI supports peer-to-peer (P2P) networking for distributed inference. The P2P API endpoints allow you to monitor connected worker and federated nodes, retrieve the P2P network token, and get cluster statistics.

For an overview of distributed inference setup, see [Distributed Inference](/features/distributed_inferencing/).

## Endpoints

### List all P2P nodes

- **Method:** `GET`
- **Endpoint:** `/api/p2p`

Returns all worker and federated nodes in the P2P network.
