# MetaproBuyNow

**BUY NOW AUCTION**

As the name suggests, a Buy Now Auction is characterized by the direct purchase of a token, where the token and funds are immediately distributed to the relevant parties upon purchase. Below, you will find information on how to distinguish this type of auction on our marketplace, along with details about possible scenarios.

**Auction Markings:** 

Buy Now Auctions have a label in turquoise and a purchase button named 'Buy Now.' These markings have been implemented to easily differentiate between auctions.

**Key Participants:**

* **Operator:** The person creating the auction.
* **Participant/Bidder:** The person participating in the auction.
* **User:** Someone unrelated to the auction, who has not purchased any tokens.

**Possible Scenarios:**

* The auction status changes to 'Ended' when all tokens are sold in that auction (no need for auction finalization by the Operator or Participants since tokens and funds are already distributed among users).
* The auction may require finalization by the Operator only when there are unsold tokens on the contract. Possible scenarios include:
  * Not all tokens were sold, and the auction has ended.
  * There were no purchase offers.
* The auction allows setting a limit for participants, determining whether a user can participate multiple times in purchasing a specific auction.
* The Operator has the right to cancel the auction before it starts.
* The Operator can purchase tokens from their own auction. This solution is introduced in case of potential errors during price or quantity setup, as the cancellation is no longer possible.

*In the next steps, we explain the Contract methods directly on the blockchain explorer*

## 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://docs.metaproprotocol.com/developer-documentation/smart-contracts/metaprobuynow.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.
