Pricing for 1Password Connect

I'm thinking of registering secret information such as tokens in 1Password and using it via the 1Password Connect server.

When I look at https://developer.1password.com/docs/secrets-automation/,
there is no mention of any costs involved in using it,
but when I look at articles about usage by other companies (https://dev.classmethod.jp/articles/1password-secrets-automation/),
it seems like there is a usage fee.

When I search, I find articles like "1Password Connect server pricing<https://developer.1password.com/docs/connect/pricing/>",
but when I actually click on it, it takes me to a different article, so I'm not sure.

Could you please tell me about the pricing structure for using 1Password Connect?

Thank you
