# Use Cases

> Common stored value lookup scenarios

Stored value lookups support a few common scenarios. Below are some examples:

<AccordionGroup>
  <Accordion title="Balance check before redemption">
    * **Scenario**: Confirm a stored value instrument's balance before redeeming it.
    * **Use Case**: A customer presents a stored value instrument, such as a voucher, and the Merchant wants to show its available balance, or verify it is valid, before starting a redemption.
    * **Behaviour**:
      * Choose the stored value `type` and provide the `source` credentials it requires. List the supported types with [`GET /collect/redemptions/types`](/api-reference/collect/redemptions/get-types).
      * Call [`POST /stored_value/lookup`](/api-reference/collect/stored-values/lookup) to fetch the balance, currency, and provider metadata.
      * If the balance is sufficient, create a redemption for the desired amount.
    * **Example**: Showing a voucher balance in a wallet top-up flow before the customer commits.
