GET /x402/v1/agents

unprobed

List or search SAN agents. Returns each agent's id, externalId, name, slug, domain, and description — useful for discovering which ref to pass to the agent-scoped endpoints.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
