About Prepaid card generator

Create prepaid-card fixtures for a payment form or funding-aware interface. The current generator uses the published Stripe Mastercard prepaid example and includes its test PaymentMethod identifier.

When to use it

Test a prepaid funding label without inventing an issuer, account, or stored balance.

Limits & privacy

Only the documented Mastercard prepaid fixture is supported. This does not issue prepaid cards, simulate balances, or generate gift-card codes. Numbers repeat, and sample values do not select new payment outcomes. Browser generation is local; hosted calls use normal quotas.

Use this tool from the API reference or connect through the SDK, CLI, SSH, or MCP. Hosted calls share your plan allowances.
