Adelphic Mobile *

Adelphic is an enterprise demand-side platform (DSP) for programmatic advertising, originally founded as a mobile-first programmatic buying platform and acquired by Viant Technology in 2017. The Adelphic DSP lets marketers plan, buy, and measure omnichannel campaigns across Connected TV, linear TV, mobile, desktop, streaming audio, and digital out-of-home from a single self-service interface, using Viant's people-based Household ID identity resolution to activate first- and third-party data and measure outcomes. It is offered as an enterprise SaaS platform with a hosted UI, online knowledge base, and certification/Programmatic University training rather than a public developer API; the adelphic.com domain now operates as a legacy redirect surface pointing to Viant's product pages. An Adelphic API service does exist and is monitored as its own component on the Adelphic status page, but api.adelphic.com answers every path with HTTP 401 and `WWW-Authenticate: Basic realm="Adelphic"`, and the knowledge base is customer-only, so no contract, reference, SDK or pricing is public. Added to the API Evangelist network as a portfolio-company profile surfaced from GV.

Adelphic Mobile * is profiled on the APIs.io network. Tagged areas include Company, Enterprise, Advertising, AdTech, and Programmatic Advertising.

Adelphic Mobile *’s developer surface includes support, engineering blog, authentication, and 15 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/adelphic-mobile: open an issue to ask a question, or submit a pull request to add artifacts.

    path across six hosts, plus a rejected dsp.viantinc.com SPA soft-200), so the pointer was asserting a surface the provider
    does not serve. No Documentation, SDKs, SecurityTxt, Deprecation, Pricing, TermsOfService, Postman, MCPServer or AgentCard
    pointer is emitted: each was probed and genuinely missed.'
