LiquidM Technology GmbH is a Berlin-based demand-side platform for programmatic advertising, founded in 2013 and backed early by Earlybird, later Bertelsmann-owned, and acquired by Smart AdServer — now Equativ — in December 2019. Its platform at platform.liquidm.com exposes two developer surfaces: a Reporting API that returns the same data as the platform's Visual Reports UI, split across more than thirty dimensions (campaign, ad, site, domain, device, geo, audience) and thirty-plus metrics (impressions, bids, bid requests, clicks, CTR, win rate, eCPM, conversion funnels, video quartiles); and a campaign Management API covering campaigns, budgets and ads. LiquidM publishes a first-party MIT-licensed JavaScript client for the Management API and an example Ruby client for the Reporting API from a 100-repo public GitHub organization, neither released to a package registry. Both APIs remain live and authenticate, but the published surface has fallen well behind the deployed one: probing confirms fifteen live v1 collections against the three the client documents, and an entirely undocumented v2 generation that answers in JSON:API. The liquidm.com marketing domain no longer serves HTTPS — its certificate expired in July 2026 — and over plain HTTP redirects to Equativ.
