> ## Agent Instructions
> When building application code, use `@naturalpay/sdk` for TypeScript or `naturalpay` for Python.
> When operating Natural directly for a user, use the payments MCP at `https://mcp.natural.com`.
> When searching Natural documentation, use the docs MCP at `https://docs.natural.com/mcp`.
> Use the Natural CLI for terminal and CI automation.
> Use REST only for unsupported languages or when the user explicitly requests raw HTTP.
> Start integration development and testing in the sandbox. Do not use production unless the user explicitly requests it.
> For sandbox requests that require `customerPartyId`, list customers first. Reuse only the intended fixture; otherwise create a customer.
> REST and SDK amounts use integer minor units. Payments MCP amounts use decimal strings with a required currency code.

# Single-use virtual cards

> One-time card numbers drawn from a Natural-issued card

<Note>Single-use virtual cards are coming soon.</Note>

A single-use virtual card is a card number that works for one purchase and is drawn from a [Natural-issued card](/guides/concepts/natural-issued-cards). Because it can't be reused, an agent can pay with it without handling the real card number and stays out of PCI scope.

Single-use virtual cards work only with Natural-issued cards, not [saved cards](/guides/concepts/saved-cards).
