  title: Maxar Geospatial Platform (Vantor Hub) Authentication Discovery API
  version: '1'
  description: 'REST API surface for the Maxar Geospatial Platform, branded in 2026 as

    Vantor Hub. This specification covers the Authentication / Token Service

    used to obtain OAuth2 bearer tokens and API keys, the Discovery API for

    STAC-style search of the Maxar catalog, and the Ordering API for

    estimating, validating, placing, and tracking orders for imagery and

    derived products. Bearer tokens are required for Admin and API Key

    operations; data-related endpoints accept either an OAuth2 bearer token

    or an API key.
