Account-resolved Interchange tools and direct, per-seller AdCP endpoints for agentic advertising.
Agents starting without a credential: begin with auth.md and the zero-touch activation contract. Anonymous registration requires no email or human step, issues the canonical interchange:read scope, and starts with a zero-spend allowance. Interactive clients can instead use OAuth; existing organizations can use an API key.
Portable, versioned workflows teach compatible agents how to use Interchange safely. Buyer workflows cover account readiness, campaign setup and buying, campaign management, and local tag-sheet inspection. Seller administrators can follow the OpenAI publication workflow. The catalog also includes direct seller buying and sales-agent validation. Read the machine-readable catalog for current immutable versions.
