Same Authorization header, plan rule and subscribe messages as the thesis feed. The token list takes coin mints:

{ "type": "subscribe", "subscription": { "type": "all" } }
{ "type": "subscribe", "subscription": { "type": "tokens", "tokens": ["<coin mint>"] } }

Each new callout arrives as one frame. callout is the record GET /v2/pump/thesis returns in items:

{
  "type": "pump_callout",
  "callout": {
    "id": "…",
    "wallet": "<author wallet>",
    "userName": "caller",
    "xUsername": "caller",
    "isVerified": false,
    "coinMint": "<coin mint>",
    "chain": "solana:mainnet",
    "coinSymbol": "COIN",
    "coinName": "Coin",
    "thesis": "Why I am in this coin…",
    "mediaUrl": null,
    "calledOutAtMcap": 48210.5,
    "multiple": 1.8,
    "maxMultiplier": 2.4,
    "createdAt": 1790000000000
  }
}

The frame also carries profileImage, the engagement counts and position, as listed in the API reference. Read callout.coinMint to route a frame to its coin. There is no replay. A callout is sent once per socket, and only while it is recent. After a drop, reconnect, subscribe again and read GET /v2/pump/thesis to pick up what you missed, matching on id. This socket bills per minute on its own, from the same credits as REST calls. To receive theses and callouts, open one socket on each path. The callout alerts bot is a complete consumer.
