Oracle Events

Event: oracle_events
Cost: 0.1 credits per delivery

Fires on on-chain oracle activity — resolution, dispute, assertion, emergency, and related event types. The full payload schema is in the auto-generated Oracle Events callback reference; this page documents the filters and matching behavior.

When to use this

Track market resolutions and settle positions as soon as the oracle reports.
Get alerted to disputes or emergency actions that may affect open markets.
Monitor assertion lifecycle activity for specific conditions you care about.

Subscription filters

Add these to the filters object when you create the subscription.

Filter	Type	Description
`oracle_event_types`	string[]	Restrict to specific oracle event types, e.g. `QuestionResolved`, `DisputePrice`, `ProposePrice` (max 500).
`condition_ids`	string[]	Restrict to specific markets by condition ID (max 500).

Example

{
  "url": "https://your-server.com/webhooks",
  "event": "oracle_events",
  "filters": {
    "oracle_event_types": ["QuestionResolved", "DisputePrice"]
  }
}

Notes

oracle_event_types narrows delivery to specific lifecycle events — set it to receive only the stages you care about (e.g. just QuestionResolved) instead of every oracle action.
