Last check, 2026-11-02 02:47 UTC: fail

• fail required field 'supportedInterfaces' is missing
• fail looks like an A2A 0.3 card (top-level url, preferredTransport, additionalInterfaces, protocolVersion); v1.0 lists endpoints in 'supportedInterfaces'
• warn v1.0 JSON uses camelCase; these keys are snake_case: x-da.key_endpoints
• warn signature 1 (kid 'LT0nvVeUTe1nOOtCeDB57JVYvidWU9Kal7bW_HS9btY', EdDSA) verifies over the card as served, not over the spec's canonical form, which drops empty fields (8.4.1); the card is unaltered, but a strict verifier will reject it
• info no JSONRPC or HTTP+JSON interface to probe
