2. Create Your First Card

Generate a virtual card with custom limits for your AI agent. Card numbers are shown once for security.

POST /v1/cards

3. Process Payments

Charge the card to pay for services. Real-time balance updates and webhook notifications.

POST /v1/payments

4. Go Live

Switch from sandbox to production endpoints. Contact us for production API access.
