What to know

  • Works alongside AP2 for payment authorization, and with MCP and A2A for agent connectivity.
  • Verticals: shopping (Etsy, Wayfair), lodging (Booking.com, Expedia, Hilton, Marriott, Trip.com), food (DoorDash, Square, Toast, Uber Eats).

When to use it

If you sell online and want AI agents to be able to buy from you without a custom integration per assistant.
