OpenXSelect API
GraphQL API (BETA) for the OpenXSelect curation platform — query providers, segments, audiences, deals and packages, and mutate audiences (create/update/archive/activate), deals, routed retargeting segments and the bidder object family (BidderOrder, BidderLineItem, BidderCreative). Authenticated with a 90-day organization-wide API key in an x-apikey header. Introspection is gated; the published reference documents ~120 objects, ~40 inputs, custom scalars and interfaces.
