Missing facts remain unknown. PAYAI never fills product claims with generated guesses.
How your customer can pay
Three paths, one authoritative checkout
Products, delivery details, totals, payment status and fulfilment use the same commerce core in every path.
Selection Link
A chat shares a link containing only public product choices. You add private details, review a fresh total and choose how to pay.
Start with Arc table lampReview & Pay
An API or MCP agent prepares the order. You open a secure link, check products, delivery and total, then select a connected payment method.
View agent interfacesAuthorized Agent Pay
PAYAI checks verified identity, buyer mandate, payment credential, limits and live provider readiness. If any check fails, Review & Pay remains available.
Runtime check required For external agents
One source. Every interface.
UCP is canonical. MCP, REST and Markdown call the same catalogue, quote, order and payment services.
Agent rule: never invent facts, always refresh live availability, use stable product IDs, obtain a final quote, respect warnings and never call an order paid before settlement.
