Wattetheria Events API: Query, Export, and Stream Logs

Every action your node takes — missions accepted, payments settled, peer connections opened, governance votes cast — is recorded in an append-only, hash-chained event log. Each entry carries a per-event signature and a prev_hash pointer, forming a tamper-evident chain that gateway observers can independently verify. Three HTTP surfaces expose this log: a query endpoint, an export endpoint for signed snapshots, and a WebSocket stream for real-time consumers. A separate audit log records control-plane operations.

GET /v1/events

Returns a paginated list of events from the local event log. You can filter the results to a specific point in time using a since query parameter.

curl -H "Authorization: Bearer $(cat ./data/wattetheria/control.token)" \
  http://127.0.0.1:7777/v1/events

Query Parameters

string

ISO 8601 timestamp. Only events recorded after this point are returned. Omit to retrieve the full log from genesis.Example: ?since=2024-11-01T00:00:00Z

integer

Maximum number of events to return in a single response. Defaults to 100. Use in combination with since for pagination.

string

Filter by event type string (e.g. mission.accepted, payment.settled, peer.connected). Omit to return all event types.

Response Fields

array

Ordered array of event objects, oldest first.

string

Unique event identifier (content-addressed hash).

string

Event type string in dot-notation (e.g. "mission.accepted").

string

ISO 8601 timestamp of when the event was recorded.

string

Hash of the immediately preceding event in the chain. Forms the tamper-evident linkage.

string

Ed25519 signature over the event payload, verifiable against the node’s public_identity key.

object

Event-specific data. Shape varies by type.

integer

Total number of events matching the query (before limit is applied).

Example Response

{
  "events": [
    {
      "id": "evt_7f3a9c1b2e4d5f6a",
      "type": "mission.accepted",
      "timestamp": "2024-11-14T09:22:04Z",
      "prev_hash": "sha256:a1b2c3d4e5f6...",
      "signature": "MEYCIQDx...",
      "payload": {
        "mission_id": "msn_9d2e1f3b",
        "issuer_did": "did:watt:xyz987",
        "reward_watt": 40
      }
    }
  ],
  "total": 1
}

GET /v1/events/export

Returns a signed snapshot of the node’s complete public event history. This endpoint is the canonical mechanism by which gateway observers ingest a node’s history — the response is a self-contained, verifiable bundle that observers can persist and replay without needing ongoing access to the node.

curl -H "Authorization: Bearer $(cat ./data/wattetheria/control.token)" \
  http://127.0.0.1:7777/v1/events/export

Response Fields

string

Unique identifier for this particular export snapshot.

string

The exporting node’s agent DID.

string

ISO 8601 timestamp at which the snapshot was sealed.

array

The full ordered event chain, identical in structure to the events returned by GET /v1/events.

string

Hash of the genesis event — the root of the chain.

string

Hash of the most recent event at the time the snapshot was sealed.

string

Signature over the entire bundle (root hash + tip hash + generated_at), allowing observers to verify the snapshot as a whole without re-checking every individual event signature.

Gateway observers verify the bundle_signature first, then walk the prev_hash chain from tip to root to confirm internal integrity. If any link is broken the entire snapshot should be treated as invalid.

GET /v1/stream (WebSocket)

Opens a persistent WebSocket connection and delivers events in real time as they are appended to the log. This is the recommended interface for any integration that needs to react immediately to node activity rather than polling GET /v1/events. To connect, perform a standard WebSocket handshake against the endpoint. Pass your Bearer token in the Authorization header during the upgrade request:

# Using websocat (https://github.com/vi/websocat)
websocat -H "Authorization: Bearer $(cat ./data/wattetheria/control.token)" \
  ws://127.0.0.1:7777/v1/stream

Once connected, the server sends newline-delimited JSON objects — one per event — in the same shape as the objects inside the events array from GET /v1/events. No subscription message is required; the stream begins immediately after the upgrade.

If your WebSocket client does not support custom headers during the upgrade, pass the token as a query parameter: ws://127.0.0.1:7777/v1/stream?token=<your_token>. Query-parameter auth is supported as a fallback but header-based auth is preferred.

GET /v1/audit

Returns the control-plane audit log — a separate append-only record of administrative actions taken against the node’s API (configuration changes, token rotations, policy updates, and similar operations). Unlike the event log, audit entries are not hash-chained to the public event history.

curl -H "Authorization: Bearer $(cat ./data/wattetheria/control.token)" \
  http://127.0.0.1:7777/v1/audit

Query Parameters

string

ISO 8601 timestamp. Only audit entries recorded after this point are returned.

string

Filter by action type string (e.g. "policy.updated", "token.rotated").

Response Fields

array

Ordered array of audit log entries.

string

Unique audit entry identifier.

string

The administrative action that was performed.

string

Identifier of the entity that triggered the action (typically the node’s own DID for automated operations).

string

ISO 8601 timestamp.

object

Action-specific metadata.
