Buy a Product

This tutorial walks you through the process of buying a product on NumerBay.


You need to have a NumerBay account with Numerai API Key in order to make purchases on NumerBay.

It is also recommended to Generate a key pair as some products use client-side encryption.


Some products use client-side encryption and are delivered on a per-order basis. It is therefore recommended to buy before the tournaments start.

Checkout and payment

Place an order

Navigate to a product you are interested in, and click Buy. Then, select your preferred product option and the quantity (number of rounds) of that product option you would like to buy, read the disclaimer, and click Place an Order.

If the product you are buying is a tournament submission, you can select a model slot to auto-submit to. This is mandatory if the product is sold in "Stake Only" mode.

If you have a valid discount coupon for the product, you can also apply it before placing an order.

Product Quantity


The quantity selected here is the number of tournament rounds based on the pricing option selected.

Each week consists of 5 daily rounds, therefore enter 5 if you want to buy for a week. Alternatively you can use the advanced calendar date picker to select specific days to buy.


After placing an order, you will see the payment instructions. Copy the address and amount to make a payment via your Numerai wallet. You can leave this page if you want to.

Your orders are viewable in the Purchases page. Orders are typically confirmed within 30 seconds after payments are confirmed on-chain.


Payment needs to be made in full and in one single transaction from your Numerai wallet within 45 minutes after order creation. If no matching payment transaction is found within the time limit, the order will expire.

NumerBay currently does not fully support payment from arbitrary NMR wallet, DO NOT send NMR from your own wallet or exchange wallets.

Product Payment

Download artifacts

Head to the Purchases page. Click the download button next to your order to view the list of downloadable artifact files. Then, click on the file name to download the file.

If you purchased before Numerai tournament round starts, artifacts may not be available for immediate download. Sellers will be notified of your order and will upload artifacts once the tournament round starts. You cannot download artifacts for past rounds.

It is recommended to place orders early so sellers would have enough time to fulfill the upload.

Advanced tip

You can also download via the NumerBay Python / Cli Client, head over to the API Tutorial for examples.

Order List


If the product you bought uses client-side encryption, you may be prompted by MetaMask to decrypt your NumerBay key in order to decrypt the file.



If you made your order with auto-submission set up during checkout, submissions will be automatically done for you after tournament round open and after the seller submits their files.

Change auto-submit model slot

You can change the auto-submit destination model in the order details panel which can be opened by clicking on the View details button in the Purchases page.
