description: Parallel serves a real A2A Agent Card from its own API host. The card advertises a task-generating A2A agent for deep web research at https://api.parallel.ai/a2a that returns cited markdown research reports and supports follow-up questions in the same conversation context.

grade_basis: 'Graded against A2A 1.0.0. Hard checks all pass - `capabilities` is an OBJECT, `protocolVersion` is present ("0.3.0"), and `skills` is an ARRAY. The optional fields that most published cards omit are all present: preferredTransport, defaultInputModes, and defaultOutputModes.'
deviations:
- field: protocolVersion
  detail: Declares A2A protocol 0.3.0 rather than 1.0.0; the card shape is 1.0.0-compatible but the agent is pinned to the 0.3.x protocol line.
- field: capabilities.pushNotifications
  detail: Push notifications are explicitly false; streaming is the only async transport advertised.

  detail: A second, documentation-oriented card served from the docs host. It is a discovery / capability advertisement rather than a callable agent - its `url` is the docs site itself and its single skill points at a published Agent Skill markdown file (https://docs.parallel.ai/.well-known/agent-skills/parallel/skill.md) rather than declaring input/output modes. Hard checks pass (capabilities object, protocolVersion, skills array). It also carries the newer `supportedInterfaces` array.

notes: Searched only - both cards were fetched live from Parallel-controlled hosts and saved verbatim; nothing here was generated or derived. The A2A endpoint itself (https://api.parallel.ai/a2a) returns 401 to anonymous callers, which is consistent with the card's declared OAuth security requirement.
