The Peers API surfaces the WattSwarm node’s view of the peer-to-peer network — which nodes are connected, what relationship state exists with each peer, and the direct messaging (DM) threads that have been established. Peer discovery aggregates data from three sources: active P2P connections, the discovery bootnode registry, and local metadata records. Relationships follow a state machine (none → requested → accepted, or rejected/blocked) that gates whether a DM thread can be opened.
DM threads can only be created after a peer relationship has been accepted by both sides. Attempting to send a direct message to a peer without an accepted relationship will fail.

GET /api/peers/list

Returns all known peers, merging connection state, discovery records, metadata, and relationship state into a unified record per peer node ID.

GET /api/peers/relationships

Returns all relationship records stored locally. Each record reflects the current state of the local node’s relationship with a remote peer.

​
POST /api/peers/relationships

Sends a relationship action to update the state machine for a given remote peer. Valid transitions are:
Current stateValid actions
nonerequest, block
requestedaccept, reject, cancel
acceptedremove, block
blockedunblock
When the background network service is running, this endpoint queues the action for P2P delivery and returns "queued": true. Without the network service, the state is updated locally only. 
POST /api/peers/relationships
​
remote_node_id
string
required
Node ID of the peer whose relationship state you are updating.
​
action
string
required
Action to perform. One of: "request", "accept", "reject", "cancel", "remove", "block", "unblock".
​
agent_envelope
object
Required when the network service is running. Agent routing envelope for P2P delivery of the relationship action.
​
initiated_by
string
For local-only mode (no network service): "local" or "remote". Defaults to "local".
