  title: AgenticAdvertising.org Registry API
  description: >-
    REST API for the AgenticAdvertising.org registry. Resolve brands,

    discover properties, look up agents, and validate authorization in the

    AdCP ecosystem.


    Most endpoints are public and require no authentication. Endpoints marked

    with a lock icon accept either an organization API key or a user JWT

    obtained via the OAuth 2.1 flow — see
    [Authentication](https://agenticadvertising.org/docs/registry/index#authentication).

  - name: Onboarding
    description: >-
      Explicitly bootstrap a third-party integration into the AAO registry. Most
      callers don't need this tag — `POST /api/me/agents` auto-creates the org
      (for fresh users) and the member profile (for first-time agent
      registration) without a separate round trip. Use `POST /api/organizations`
      only when you need to override the auto-derived org name / company_type /
      revenue_tier. Tier transitions happen via the billing flow only; the
      Stripe webhook is the sole writer of `organizations.membership_tier`.
  - name: Member Agents
    description: >-
      Register, list, update, and remove agents on the caller's organization
      member profile. Authenticated programmatic surface for CI / scripts that
      don't want to round-trip the full member profile.
