# The Store

The Store is where you buy Keys.

Open it from HQ or navigation.

![The Store](https://cdn.jsdelivr.net/gh/dropbear-hl/size-docs-assets@master/store.png)

## What you can buy

| Item            | Price | What you get                                      |
| --------------- | ----- | ------------------------------------------------- |
| Alpha Trial Key | $1    | One Trial attempt. Win to earn a $100 Alpha Life. |

Larger Key tiers ship later. The Store sells Alpha Keys only for now. See [Product tiers](/docs/how-size-works/product-tiers-keys-and-lives.md).

## How purchase works

1. Select the Alpha Trial Key.
2. Pay from your wallet balance (USDC).
3. The Key appears in Inventory as Unused.

If you need USDC, [add funds](/docs/wallet-and-store/add-funds.md) first.

## Your free Key

Signup grants one free Alpha Key. You do not need to buy until you have used that one.

## After purchase

* Keys sit in Inventory until you start a Trial.
* The Key is consumed when the Trial starts.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://size.club/docs/wallet-and-store/the-store.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
