# getpeerinfo - Zcash

This method returns detailed information about each connected peer. Post-Zebra 3.0.0, the response was extended with `subver`, `version`, `services`, `lastrecv`, `banscore`, and `connection_state` fields — bringing parity with Bitcoin Core's peer info surface and enabling detailed network diagnostics.

## Parameters

This method takes no parameters.

## Use Cases

* **Peer Health Diagnostics**: Detect stalled peers via `lastrecv` gaps and elevated `pingtime`
* **Client Diversity Monitoring**: Track `subver` distribution to measure network client diversity
* **Ban Score Alerts**: Alert on peers approaching the ban threshold (typically 100)
* **Connection State Debugging**: Use `connection_state` to diagnose handshake failures
