Using opencode with Anthropic OAuth violates ToS & Results in Ban

[johnellison]

Description

I've been using Claude code for months and only recently started to use Open Code.

I logged in via the OAuth method as suggested on Open Code's website and upon upgrading from Claude Max 5 to Claude Max 20, I think I triggered some kind of review and they banned my account.

I reached out to several Anthropic engineers on Twitter and discovered that using Claude in this way on Open Code violates their terms of service and results in a ban.

Open Code should no longer allow users to log in to any of the OAuth subscriptions because this violates all their terms of service. Users should be using the API key and paying for tokens by the API access.
