# Claim

> Build the claim call that pays out a matured Upshift redemption to the user's address.

> [!NOTE]
>
> Upshift vaults only (`withdrawalMode: "queued"`). Sending a Morpho vault to this endpoint returns `400`. For Morpho, use [Withdraw](https://docs.base.org/sdks/base-earn/api-reference/withdraw.md).

Builds the `claim` call for a matured queue entry. The vault pays out everything queued for that date to `address`. The API simulates the claim first, so a premature or empty claim returns `422` with the reason.

## Body Parameters

**address** `string` *required*

The share holder and receiver of the claim.

**vaultId** `string` *required*

From the approved [vault catalog](https://docs.base.org/sdks/base-earn/api-reference/list-vaults.md).

**claimDate** `string` *required*

The UTC queue date you confirmed and persisted from the mined request-withdraw transaction, formatted as `YYYY-MM-DD`.

**builderCode** `string` *required*

Required. The registered builder code for your app.
