Yahoo Ad Tech DataX API is one of 5 APIs that [Yahoo](https://apis.io/providers/yahoo/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Advertising, Audience Data, Data Exchange, Taxonomy, and GDPR. The published artifact set on APIs.io includes API documentation, an API reference, a getting-started guide, authentication docs, and rate-limit docs.

Partner-facing data-exchange API for uploading and managing audience taxonomies, user and audience membership, fees and measurement feeds, plus a Real-Time API (specification v2.0), a Partner Match data-in API and exposure-log delivery to Amazon S3, Microsoft Azure and Google Cloud. Onboarding is a manual RSA key exchange with Yahoo data operations. It is the only Yahoo API surface with hypermedia affordances, returning typed link relations under datax.yahooapis.com/rels/ and opaque resource links. GDPR handling - jurisdiction flags, IAB TCF consent purpose bits and opt-out semantics - is documented in depth.
