Limits & privacy

These are reusable provider test numbers, not newly issued cards or live payment credentials. Numbers can repeat. Use Stripe’s test environment; compatibility with other providers is not guaranteed. Browser generation stays local. Hosted calls use normal tool quotas.

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