description: 'Magnite, Inc. (NASDAQ: MGNI) is the world''s largest independent sell-side advertising platform, headquartered
  in New York with major operations in Los Angeles. Formed in 2020 from the merger of Rubicon Project and Telaria, and expanded
  through the acquisitions of SpotX (2021), SpringServe (2021), and Streamr.ai (2025), Magnite operates an omnichannel SSP
  spanning Connected TV (CTV), online video, display, audio, and mobile in-app. Its flagship offering is the Magnite Streaming
  platform — a next-generation CTV/OTT solution that unifies the SpringServe ad server with Magnite''s Streaming SSP — alongside
  DV+ for display/video web and mobile, ClearLine for agency self-service direct buying of premium video, and Magnite Access
  for first- and third-party data activation. Magnite connects publishers including Disney Advertising, Paramount, Roku, Samsung,
  LG Ad Solutions, and Warner Bros. Discovery to virtually all major DSPs, and Jounce Media''s March 2025 Supply Path Benchmarking
  Report verified Magnite reaches 99% of US streaming supply on a dollar-weighted basis. The company exposes developer surfaces
  through the SpringServe REST API, the Magnite Streaming Public API, the Magnite Seller Platform / CTV Platform Public APIs,
  an OpenRTB v2.5 bidder integration, and iOS/Android in-app SDKs. The SpringServe UI API publishes a real, anonymously reachable
  OpenAPI 3.1.2 contract in two concurrent versions (v0, 289 operations; v1, 379 operations) from the Swagger UI at https://api.springserve.com/api-docs,
  with the callable base at https://console.springserve.com. The Magnite Streaming and Seller Platform reference material
  on help.magnite.com remains gated behind an authenticated partner login. In Q1 2026 Magnite reported $164.4M revenue with
  CTV crossing 51% of contribution ex-TAC for the first time.'

  description: 'The SpringServe ad server REST API — the machine-readable core of Magnite Streaming. Two versions run concurrently:
    v0 (289 operations, 173 paths) and v1 (379 operations, 295 paths, 139 component schemas). Covers supply tags and supply
    routers (publisher inventory), demand tags (buyer demand), creatives across video/audio/tile/tag formats, deal lists and
    curated marketplaces, partner segments and audiences, targeting lists (geo, domain, app bundle, IP, postal code, ISP),
    forecasting, dashboards, a synchronous and asynchronous reporting engine with saved templates and schedules, and a first-class
    object-change audit log. Authentication is a token or JWT bearer minted at POST /api/v{0,1}/auth; there is no OAuth and
    no scope surface. Both OpenAPI 3.1.2 documents are served anonymously from the Swagger UI at https://api.springserve.com/api-docs.'
