note: Criteo serves a real A2A Agent Card from its developer-portal host. The card describes the "Criteo Docs" agent, which fronts the Retail Media API (the HookLogic product line) and the Marketing Solutions API documentation, and it advertises a single published Agent Skill. The API host itself (api.criteo.com) returns 404 for both card paths — only the docs host serves one.

deviations:
- protocolVersion is '0.3', not A2A 1.0.0 — the card uses the pre-1.0 field set (supportedInterfaces rather than additionalInterfaces).
- No top-level `description` field on the card.
- capabilities declares streaming false and pushNotifications false, and there is no extensions block, so the agent surface is request/response only.
- skills[] entries carry an empty tags[] array.

  note: The same docs host serves a live remote MCP endpoint at https://developers.criteo.com/mcp — the agent card and the MCP server are two faces of the same Mintlify-hosted documentation agent.

  note: The skill the card points at, saved verbatim.
