Agent-to-Agent (A2A 0.3.0) surface for "MERCURY Web Fetch", published as a conformant agent card at https://network.mercury-hq.com/.well-known/agent-card.json (and the legacy /.well-known/agent.json, byte-identical) with one skill (web-fetch), JSONRPC preferred transport, an x402 security scheme (pay per call, $0.003 USDC on Base) and an ERC-8004 registration (agentId 54791 on eip155:8453). The JSON-RPC endpoint https://network.mercury-hq.com/a2a implements message/send only (tasks/get answers -32601 "Mercury implements message/send"); an unpaid message/send returns a free preview with the page title and status and points at the paid /buy/fetch route. GET on /a2a 307-redirects to the card.
