XGuard

XGuard A2A Agent

Agent2Agent surface: an agent card served identically from https://api.xguardgate.com/.well-known/agent-card.json (the canonical location named in the provider's own xguard.json manifest) and from xguardgate.com, at both the A2A 1.0 path and the legacy /.well-known/agent.json path, as application/a2a+json. The card (version 5.1.0) declares one JSONRPC interface at https://api.xguardgate.com/a2a with protocolVersion 1.0.0, four skills that mirror the four REST outcomes (extract-preview, web-extraction, product-offers, feed-digest), an x402 v2 paid-execution extension pointing at the payment manifest, and streaming, push notifications and extended card all false. The JSON-RPC endpoint answers a GET with the card itself plus a discovery block, and answers every other JSON-RPC method (tasks/get, agent/getAuthenticatedExtendedCard) with A2A error -32004 Unsupported operation naming SendMessage as the only operation it implements.
