Last check, 2026-11-02 02:55 UTC: warn

• warn looks like an A2A 0.3 card (top-level url, protocolVersion); v1.0 lists endpoints in 'supportedInterfaces'
• info https://adcontextprotocol.org/extensions/adcp carries no version in its path; a breaking change then has no new URI to move to (4.6.3)
• info declares https://adcontextprotocol.org/extensions/adcp
• warn supportedInterfaces[0].protocolVersion is 0.3.0; current is 1.0
• warn skill ids appear more than once: ['get_signals']
• warn v1.0 JSON uses camelCase; these keys are snake_case: capabilities.extensions.[0].params.adcp_version, capabilities.extensions.[0].params.protocols_supported, capabilities.extensions.[0].params.skills_supported
• info no 'documentationUrl'
• info endpoint https://a2a.bidmachine.io/a2a requires authentication (HTTP 401); not probed further
• info endpoint https://a2a.bidmachine.io/a2a requires authentication (HTTP 401); not probed further
