🇺🇸Marketing & Advertising in United States

254 marketing & advertising providers in United States, publishing 3750 APIs.

254 providers 3750 published APIs 3768 indexed documents

Marketing & Advertising in United States — 254 providers on the APIs.io network sit in both cohorts, and between them they publish 3750 indexed APIs.

160 of the 254 publish at least one machine-readable API; 94 publish nothing indexed at all. That split is the first thing worth reading here — a vertical can be well represented in a market and still have almost no programmable surface.

By Kin Score band: 57 minimal, 50 exemplar, 45 emerging, 41 strong, 28 thin, and 25 developing.

Leading by rating: HubSpot, Salesforce, SendGrid, ZoomInfo, Amazon Clean Rooms, Amazon Pinpoint, and 248 more.

Country membership reads a tag, a stated headquarters or a stated nationality. A provider lands in United States when one of its own top-level tags names the country, when its own description states a headquarters that names the country or one of its cities, or when it describes itself by nationality (“a French company”; roadmap#542, #719). Region words (“Latin American”), language uses (“French-speaking”) and a city named outside a headquarters statement are not counted, so this cell is a floor, not a census.
