BidMachine

BidMachine is a mobile in-app ad exchange and monetization platform (BidMachine, Inc., McLean, Virginia; spun out of the Appodeal/Stack group) that sells publishers' mobile inventory to demand partners through real-time OpenRTB 2.5 auctions. Publishers integrate the BidMachine SDK (Android, iOS, Unity) or the newer unified BidMachine Plus mediation SDK, or plug BidMachine into AppLovin MAX, Unity LevelPlay, AdMob/GAM or TopOn as a bidding adapter; DSPs and agencies buy through the exchange. Its public APIs are a Placement Management API (create, list, update and delete placements on an ad source with a short-lived bearer token) and a Reporting API (SSP, bidder and P2P revenue reports as NDJSON or CSV over HTTP Basic), both documented as OpenAPI on developers.bidmachine.io, plus the OpenRTB auction endpoints (api-eu / api-us / api-apac) for in-house bidders and supply partners.

BidMachine publishes 4 API contracts indexed on the APIs.io network, including Authentication API, Placements API, Reporting API, and 1 more. Tagged areas include Advertising, AdTech, Mobile Advertising, Ad Exchange, and Ad Mediation.

BidMachine’s developer surface includes documentation, API reference, getting-started guide, engineering blog, signup flow, changelog, sandbox, and 41 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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/bidmachine-io: open an issue to ask a question, or submit a pull request to add artifacts.
