Agent-to-Agent JSON-RPC endpoint at https://getamber.dev/api/a2a implementing message/send, tasks/get and tasks/cancel (tasks are processed synchronously), discovered through an agent card served at /.well-known/agent-card.json and the legacy /.well-known/agent.json on both getamber.dev and ambr.run. The card declares six skills (create_contract, list_templates, get_contract, verify_hash, get_status, agent_handshake), apiKey and x402 security schemes, an MCP additional interface, a live pricing source and compliesWith urn:ambr:ricardian-v1; it is graded flavored against A2A 1.0.0 because it carries no top-level protocolVersion.
