Sharethrough

Sharethrough is an omnichannel programmatic advertising exchange (SSP) for native, display, video and CTV inventory, and one of the largest independent ad marketplaces. Publishers monetise through the Prebid.js header-bidding adapter and server-to-server OpenRTB; demand partners buy through the exchange. Two API surfaces exist: a bearer-token Publisher Reporting API at publisher-api.sharethrough.com/v2 whose public reference is now behind a support-site sign-in, and the unauthenticated OpenRTB bid endpoint at btlr.sharethrough.com/universal/v1 used by the Prebid adapter. The company's richest machine-readable artifact is its IAB sellers.json (5,189 sellers). Sharethrough merged with Equativ in 2024 and has operated under the Equativ brand since June 2025; the Sharethrough exchange and its endpoints continue to run.

Sharethrough publishes 2 APIs on the APIs.io network. Tagged areas include Native Advertising, Programmatic Advertising, SSP, DSP, and OpenRTB.

The Sharethrough catalog on APIs.io includes 1 JSON-LD context.

Sharethrough’s developer surface includes documentation, support, engineering blog, authentication, and 22 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/sharethrough: open an issue to ask a question, or submit a pull request to add artifacts.

  description: REST-ish reporting API enabling publishers to pull programmatic performance data for their Sharethrough inventory.
    A single POST /v2/programmatic endpoint takes a query object (startDate, endDate, groupBy, fields, filterBy) and returns
    CSV by default or JSON when negotiated by the Accept header. Bearer-token authentication. The v1 surface is retired and
    returns 503; the reference documentation now requires a support-site sign-in.
