The Trade Desk

The Trade Desk is an independent, omnichannel demand-side platform (DSP) for programmatic advertising, headquartered in Ventura, California. Its cloud-based platform — Kokai (the current flagship, succeeding Solimar) — lets agencies, brands, and trading desks buy and optimize digital ad inventory across connected TV (CTV), audio, mobile, video, native, display, and digital out-of-home. The Trade Desk positions itself as the buy-side counterweight to the walled gardens by championing the open internet through OpenPath (direct publisher integrations that bypass SSPs) and Unified ID 2.0 (UID2), an open-source, deterministic identity framework governed by the IAB Tech Lab. The company also stewards EUID (UID2's European equivalent), the Galileo first-party data activation framework, and Koa — its in-platform AI used for forecasting, bidding optimization, and audience modeling. Programmatic developers integrate via the TTD Workflows API (REST + GraphQL for campaign, ad group, and creative management), the Data API (advertiser/third-party data ingestion, offline conversions, deletion/opt-out), the Real-Time Conversion Events API (RTCE), and the OpenSincera data-quality APIs (acquired May 2024). Official SDKs are published in Python, Go, and Java and are Speakeasy-generated from OpenAPI specs. Most documentation lives behind the Partner Portal (partner.thetradedesk.com) but a public docs surface is exposed at open.thetradedesk.com. The Trade Desk is publicly traded (NASDAQ: TTD).

The Trade Desk publishes 4 APIs on the APIs.io network, including Advertiser API, DeletionOptOut API, OfflineConversion API, and 1 more. Tagged areas include Advertising, Programmatic Advertising, Demand-Side Platform, DSP, and AdTech.

The Trade Desk’s developer surface includes developer portal, documentation, getting-started guide, code examples, engineering blog, YouTube channel, and 28 more developer resources.
