It can, but the auth & communication to Anthropic's APIs is basically reverse engineered from Claude Code. While it works, and it seems Antropic is choosing to look the other way, it _may_ result in your account getting banned, as I'm pretty sure it's against their TOS.

I haven't experienced this myself, but RooCode does something similar to OpenCode's approach and the maintainer has reported some bans [1].

Google on the other hand, is being very strict about keeping you locked in to their tools, unless you use API keys, of course.
