Make sure you purchased the extension from you Magento MarketPlace account.

If that's not the case make sure that your username and password are correct in the auth.json.

Reference: https://getcomposer.org/doc/articles/http-basic-authentication.md

  • I have given the Public Key as username and Private Key as a password in auth.json. Still, it's showing the same error. Any other suggestion? or how to check my access key having privileges. Commented Apr 23, 2018 at 8:06
  • It should be your actual username and password from the market place. Have a look at the link I added to the answer.

The answer is in your question! you shared link how to install B2B in magento commerce.

In documentation there mentioned If you get an error when trying to install the B2B module for local instance of Magento Commerce (for example:)

[InvalidArgumentException] Could not find a matching version of package magento/extension-b2b. Check the package spelling, your version constraint and that the package is available in a stability which matches your minimum-stability (stable).

The same error you showing in your question and also give solution for it.

  1. Create an auth.json file in the Magento root directory and add the following code. using the actual values of you public_key and private_key for username and password:

    { "http-basic": { "repo.magento.com": { "username": "<public_key>", "password": "<private_key>" } } }

  2. When prompted, enter your authentication keys. Your public key is your username; your private key is your password. If you have stored your public and private keys in auth.json, you won’t be asked to enter them here.

  3. Run the following commands after Composer finishes updating modules:

bin/magento setup:upgrade

bin/magento setup:di:compile

bin/magento setup:static-content:deploy -f

Important After completing the installation, you must follow the post-installation steps.

For your knowledge

I hope it helps!
