Vapi launches Personal Agent Calling beta for AI agents that call businesses on customers' behalf

Vapi has launched Personal Agent Calling in beta, letting users sign in with Vapi and make calls through a personal agent without setting up an API key. The company argues businesses must verify who an agent represents, what it is allowed to do, and whether that permission still applies, building on the A2A open standard and OAuth. Forcing customers to start over risks losing their business.
