Buyer Agent API is one of 9 APIs that [IAB Tech Lab](https://apis.io/providers/iab-tech-lab/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Agentic Advertising, Media Buying, and Deals. The published artifact set on APIs.io includes API documentation and an OpenAPI specification.

IAB Tech Lab's reference buyer agent for DSPs, agencies and advertisers: an OpenAPI 3.1 REST surface (14 operations — orders and audit trails, booking jobs and approvals, product search, events, reports and campaign metadata) that drives MCP, A2A and REST clients against seller agents to browse media kits, negotiate and book OpenDirect 2.1 deals. Self-hosted; no IAB Tech Lab-hosted instance.
