Copay earns trust through product clarity, permission boundaries, and developer-grade workflows — and states only what it actually provides.

Copay U Card
Business U Card
A physical U Card program for overseas registered companies and distribution-led business customers: gated by KYB, use-case review, batches (from 200 cards), and operating rules, with full-lifecycle management of card status, balance, and activity. Invitation-only.

Agentic Payment
AI agents that pay — inside your rules
Agentic Payment lets AI agents handle procurement, subscriptions, and API spend on their own — but only within the limits, allowlists, chains, and assets you approve in advance, with every step auditable. Watch a real demo.
From collection to payout, every state is traceable
Merchants create orders through API or dashboard. Copay handles balances, rules, status updates, and webhooks. U Card and Agentic Payment are gated by business review and permissions.

Accounts, permissions, and audit live in one place — not a set of separate rails bolted together.
Agentic-native
Designed from the ground up around “humans set the boundary, agents execute,” not an AI patch added later.
Trust through controls, not badges
Credibility comes from KYB, permissions, limits, and audit logs — we do not display licenses we have not earned.
