Set up Account

In order to buy or sell on NumerBay, a NumerBay account with Numerai API key needs to be set up.

Sign up

Head to, click the Connect Wallet button on the top right of the page, and login by connecting your MetaMask wallet.


Sign-up by username has been deprecated. Users who had not connected a MetaMask wallet to their accounts can login via the legacy username login tab.

Generate Key Pair

In the Edit profile page, click the Generate Key Pair button to generate a public-private key pair that will be used to encrypt your purchased artifact files. After doing so, click Export key file to safe-keep the generated key. The exported key file can be used in the Python client to download encrypted files.


Set up Numerai API Key

After logging in, head to the NumerBay account settings for the Numerai Settings page in the sidebar.

If you don't have a Numerai API key yet, you can create one in the Numerai Account Settings page. Make sure it has at least View user info permission. NumerBay only uses user info for model ownership verification and email notifications.

Additional API permissions may be needed depending on what you want to do on NumerBay, you can always change API keys later:

Task\PermissionView user infoView submission infoUpload submissionsStake*
Buy (File Mode)✔️
Buy (with Auto-submit)✔️✔️✔️
Buy (Stake Only Mode)✔️✔️✔️
Buy (with Stake Limit)✔️✔️✔️✔️

[*]: Stake permission is only used to down-adjust stake below the product's stake limit if exceeded

After creating an API key with the permissions required, plug them into the form as shown below, wait for a few seconds for validation, and the updated API Key permission info will be reflected: Numerai API Key

When you changed your model names or created new model slots, it's recommended to refresh the API using the refresh button on the top right.


If you encounter errors while updating with a valid Numerai API key, it may be likely that you are not logged in with the correct NumerBay account, you might have another old account bound to the same Numerai account. Please check if you are logged in with the correct MetaMask wallet or if you have an old account or account created with username.

Update profile

You can change your username, password and email in the Edit profile page. By default, your Numerai email address is used to receive email notifications.


NumerBay does not yet allow password recovery, please contact support by posting in the #numerbay channel in Numerai Discord Server.
