Service terms

Subscription

A $39 payment activates service for 30 days and includes up to 500 paid invoices during that period. Access stops when the subscription expires or the invoice allowance is reached.

Merchant responsibilities

• Keep the API key confidential and use it only from trusted backend systems.
• Supply correct wallet addresses and verify integration before accepting customer orders.
• Fulfill an order only after the authenticated API returns PAID.
• Create a new invoice after an invoice becomes EXPIRED.

Blockchain payments

Blockchain transactions are irreversible. Network availability, confirmation timing, token contracts, and wallet access operate outside Unsu. Merchants remain responsible for their wallet addresses and access to those wallets.

Service operation

Unsu may limit or suspend abusive traffic, attempts to bypass service controls, or activity that threatens service availability. Features, supported networks, and limits may be updated as the service develops.
