notes: Parallel serves TWO A2A Agent Cards from its own hosts. The primary card (api.parallel.ai) describes a real, callable A2A agent — "Parallel Deep Research" — whose endpoint https://api.parallel.ai/a2a answers a JSON-RPC POST with HTTP 401 (Apigee OAuth key challenge), confirming a live auth-gated A2A surface rather than a static document. A second, lighter card on the docs host points at the documentation site and links a published Agent Skill.

  - protocolVersion is 0.3.0, the pre-1.0 A2A revision. The card carries no hard failure against A2A 1.0.0 shape checks, but it is not declared against 1.0.0.

  deviations:
  - The card's `url` and `provider.url` both point at the documentation site (https://docs.parallel.ai/) rather than an A2A message endpoint, so the card advertises discovery/skill metadata more than a callable A2A agent.
  - protocolVersion is '0.3' (pre-1.0), and the single skill declares an empty tags[].
