SelfVend

A store operator may want software agents to discover products, availability or policies and later request actions such as cart creation or order placement. Publishing an endpoint is easy compared with deciding which agent represents whom, what it may see, what payment covers and who authorizes a consequential write. SelfVend packages that governance boundary.

The source confirms a live vertical product with public discovery, self-registration and read-versus-write tiers, plus several developer payment primitives. The remaining non-developer productization gap is plausible but thin. A one-day install, universal discovery or default paid write cannot be promised from the supplied evidence.

Agent observation, software identity, verified principal, delegation, scope, price quote, payment authorization, merchant policy, human or principal approval, destination instruction, provider acknowledgment, order readback, settlement and fulfillment remain separate. Payment never grants authority by itself.

A small ecommerce operator or platform implementer that wants agent-readable public data and tightly governed transactional actions without building the entire access layer.
