- Agent payments use a one-time Stripe token capped at the order price; nothing is mailed until payment is approved.
Field notes
The page describes several ways to prepare mail: an AI-agent connection, a REST API, or a web form. For letters, it also accepts PDFs up to six pages and says an address page is added before printing. The listed destinations include Puerto Rico, US territories, and APO/FPO/DPO addresses; the service says mail can be sent from anywhere.
