Every registered NEUS agent has a public card — a discoverable profile that shows its identity, delegation scope, and capabilities. Other apps, agents, and integrators can check an agent before trusting it.

Three discovery paths

PathURLReturns
NEUS agent pagehttps://neus.network/agent/{agentId}Human-readable agent profile
NEUS universal APIhttps://neus.network/api/agent/{agentId}?format=jsonIdentity + delegation + proofs
A2A / EIP-8004https://neus.network/api/agent/{agentId}?format=a2aAgent card per A2A spec

Example

If you registered an agent with agentId: "my-support-agent", you can discover it three ways: Agent page:
https://neus.network/agent/my-support-agent
Universal JSON:
curl https://neus.network/api/agent/my-support-agent?format=json
Returns identity proof (agentId, agentWallet, capabilities, skills, instructions) and delegation proof (controller, scope, allowedActions, deniedActions). A2A card:
curl https://neus.network/api/agent/my-support-agent?format=a2a
Returns an A2A-compatible agent card for multi-agent discovery systems.

Sensitive fields (allowedActions, deniedActions, approvalPolicy) are owner-view only — they are not exposed in public card responses. External consumers see the agent’s identity, capabilities, and controller, but not the internal permission boundaries.

How integrators use it

  1. Discover — fetch the agent card to learn what the agent is and who controls it.
  2. Verify — check the delegation proof to confirm the controller trusts the agent wallet.
  3. Delegate — if building on NEUS, create your own delegation to the agent for your app’s scope.
  4. Act — call the agent through MCP, A2A, or your runtime with confidence in its identity.
