By default the response includes an embedded `venueMarkets` array. DEPRECATION: embedded `venueMarkets` is deprecated and will be removed — fetch the event's markets from GET /venue-markets?venueEventId=. To opt into the lean response now (no `venueMarkets`), send the `expand` query without `markets` (e.g. `?expand=`); send `?expand=markets` to pin markets inline across the future default change. ## OpenAPI ````yaml /openapi/openapi.json get /venue-events/{id} openapi: 3.0.2 info: title: AGG API version: 1.0.0 description: >- Prediction market aggregator REST API — authentication, users, venue events, venue markets, orderbooks, charts, and execution workflows. servers: - url: https://api.agg.market description: Production - url: https://api.staging.agg.market description: Staging security: [] paths: /venue-events/{id}: get: tags: - Discovery summary: Get Venue Event description: >- Returns a single venue event.

List responses return one row per matched cluster, and for a matched event this id is the cluster anchor — the handle to use for cross-venue lookups. Re-resolve it from discovery rather than storing it as a permanent key: clusters can merge, after which the id remains a valid event but is no longer the cluster head.
