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).
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles The Trade Desk the way a machine reads it — 12 machine-readable artifacts across 8 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — The Trade Desk scores 33.0/100 (thin), with a separate agent-readiness read of 39/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile The Trade Desk
Each block below is one kind of artifact we hold for The Trade Desk. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 8
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

Where a provider ships GraphQL, the schema is the contract. We profile it alongside the REST surface so the whole interface is legible in one place.

GRAPHQLSecurity Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.
