# Overview

> Check stored value balance and metadata before redeeming

A stored value lookup is a stateless query against a provider that returns the balance and metadata of a stored value instrument, such as a voucher, without creating a redemption.

Use it to validate an instrument or to show its balance to a customer before you redeem it.

### Stored value types

* **Voucher**: supported today, through OTT Mobile and Blu Voucher.
* **Gift Cards**: coming soon.

### Key points

* **Stateless.** A lookup is a read that does not create or change a redemption.
* **Provider scoped.** Pass the `type` and the `source` credentials the provider requires, the same shape used to create a redemption. List the supported types with [`GET /collect/redemptions/types`](/api-reference/collect/redemptions/get-types).
