  "edge": [{"source": "cid1", "target": "cid2"}, ...],
  "frontier_id": ["cid3", "cid4"]
}

GET/api/frontier

Current frontier experiments. Optionally filter by GPU class.

Query parameter

gpu	GPU class filter (e.g., RTX_4090)

Response

[ExperimentRecord, ...]

GET/api/experiment/{cid}

Single experiment by CID.

Response

ExperimentRecord

GET/api/experiment/{cid}/ancestor

Ancestor chain from the given experiment back to genesis.

Response

[ExperimentRecord, ...]  // ordered from target to genesis

GET/api/leaderboard

Node reputation scores, ordered by score descending.

Response

[{
  "node_id": "a7f3c9d1...",
  "score": 12.5,
  "experiments_published": 42,
  "experiments_verified": 38,
  "verifications_performed": 15,
  "disputes_won": 2,
  "disputes_lost": 0
}, ...]

WS/ws

WebSocket endpoint for real-time experiment updates. Connect and receive JSON messages whenever a new experiment is gossiped to the node.

Message format

{
  "event": "experiment",
  "data": ExperimentRecord
}

The connection automatically reconnects on disconnect. Send any text message to keep the connection alive (the server ignores client messages).

ExperimentRecord schema

All API responses that include experiments use this JSON shape. See Core Concept for field descriptions.
