What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of knowyourmodel.ai controls every word below.

Agent Discovery

Search the public registry or retrieve an agent record using search_agents and get_agent.

discoverysearchregistry

Examples it gives

{"operation":"search_agents","arguments":{"query":"planning"}}

Model Discovery

List public registry entities using list_models.

discoveryregistrymodels

Examples it gives

{"operation":"list_models","arguments":{"type":"model"}}

Trust and Health

trustverificationhealth

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: Nexartis — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 1.0.0
Extensions: https://nexartis.com/extensions/kym-registry/v1
Structured registry operations carried in exactly one application/json message data part.

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness: complete all eight fields required by a2a.proto v1.0
