The card names itself "Postiz Documentation" and its provider organization is Postiz Documentation, so the document belongs to this company. api.postiz.com and postiz.com both returned 404 for both the canonical and the legacy /.well-known/agent.json path. conformance: spec: A2A 1.0.0 grade: conformant protocol_version: '0.3' preferred_transport: HTTP+JSON hard_checks: capabilities_is_object: true protocol_version_present: true skills_is_array: true optional_fields: preferred_transport: true default_input_modes: true default_output_modes: true deviations: - supportedInterfaces-instead-of-additionalInterfaces deviation_notes: >- The card carries `supportedInterfaces` rather than the A2A 1.0.0 `additionalInterfaces` field. Every hard conformance check still passes (capabilities is an object, protocolVersion is present, skills is an array) and all three optional fields are present, so the card grades conformant with that one naming deviation recorded. card: name: Postiz Documentation url: https://docs.postiz.com/ version: 1.0.0 organization: Postiz Documentation documentation_url: https://docs.postiz.com/ capabilities: streaming: false push_notifications: false default_input_modes: [text/plain] default_output_modes: [text/plain] skills: 1 skill_ids: [postiz] skill_urls: - https://docs.postiz.com/.well-known/agent-skills/postiz/skill.md file: postiz-agent-card.json related: agent_skill: skills/postiz-provider-skill.md mcp_server: mcp/postiz-mcp.yml note: >- The card's single skill points at a provider-published Agent Skill markdown file, not at an A2A or MCP endpoint.
