Agent2Agent 1.0 surface: an agent card at https://machinerealms.com/.well-known/agent-card.json (version network-alpha-2) declaring two interfaces — JSON-RPC at https://machinerealms.com/a2a and HTTP+JSON at /a2a/v1 — and twelve read-only skills: network registry, realm evidence, machine-readable offers, authority boundary, intent match, capability vocabulary, agent counterparty contract, machine-native experience research, research data exchange, research intelligence, Research Commons and bounded research quests. The JSON-RPC endpoint answers tasks/get with A2A error -32001 task_not_found for an unknown id; streaming, push notifications and the extended card are declared unsupported; the card grants no write authority.
