Liquid M

LiquidM Technology GmbH is a Berlin-based demand-side platform for programmatic advertising, backed by Earlybird. 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. The liquidm.com marketing domain now redirects to Equativ, though the platform host and its APIs remain reachable.

Liquid M publishes 5 APIs on the APIs.io network, including Ads API, Authentication API, Budgets API, and 2 more. Tagged areas include Company, Advertising, AdTech, Demand-Side Platform, and Programmatic Advertising.

Liquid M’s developer surface includes developer portal, signup flow, authentication, code examples, and 16 more developer resources.
