# Prediction Metadata

Streams the same payload as [`predictionMeta`](/api-reference/info-endpoints/prediction-meta). No user address is required.

## Subscribe

```json theme={null}
{ "method": "subscribe", "subscription": { "type": "predictionMeta" } }
```

## Message

```json theme={null}
{
  "channel": "predictionMeta",
  "data": {
    "isSnapshot": true,
    "metadata": {
      "outcomeMarkets": []
    },
    "updatedAt": 1701234567890
  }
}
```

The initial message has `isSnapshot: true`. Changed payloads are published on the three-second timer with `isSnapshot: false`; each message replaces that channel's complete payload. Channels update independently and do not represent one atomic cross-market snapshot.

## Unsubscribe

```json theme={null}
{ "method": "unsubscribe", "subscription": { "type": "predictionMeta" } }
```
