The Pay3 B2B API covers card issuing, spend controls, and transaction data. The documentation is public — no account or NDA required to read the spec.
What you can offer.
Issue physical and virtual cards to your customers — cards they can use online and in store, delivered through your service.
Per-card limits, freeze and unfreeze, and transaction history. Track the state of every card you issue, from a dashboard or the API.
Stablecoin funding and balances across multiple currencies. Money in, balances, and payments — kept in one account.
Identity verification (KYC) and monitoring follow the standards of licensed partner providers. Nothing for you to build in-house.
