description: Zemanta is a native advertising and content-recommendation technology company founded in 2007 (Ljubljana, Slovenia
  and New York), best known for Zemanta One, a self-serve programmatic demand-side platform (DSP) for native advertising.
  Outbrain acquired Zemanta in 2017 and the DSP now trades as Teads DSP. The product line survived both the acquisition and
  the rebrand, and its API is live — the Teads DSP REST Campaign Management API, the former Zemanta One API, is still served
  from Zemanta-owned hosts, with the API endpoint at https://oneapi.zemanta.com/rest/v1 and a complete public reference at
  https://dev.zemanta.com/one/api/. The API covers accounts, credits, campaigns, budgets, goals, ad groups, ads, creatives,
  video assets, bid modifiers, measurement services, conversion definitions, audiences, publisher groups, deals, keyword lists,
  reporting and real-time statistics. Authentication is two-legged OAuth 2.0 client credentials; access is granted through
  a sales relationship rather than self-service sign-up. The console host one.zemanta.com 301-redirects every path to the
  matching path on dsp.outbrain.com.
