Claude Code via API Gateway: Which Models Can Handle the Agentic Loop

⚡ The gist in 5 seconds - Claude Code doesn't only work with Anthropic: requests can be routed through a compatible API gateway. - The Just AI team showed how to set this up and listed models that support the agentic loop. - Details are in the article on Habr. ### 🔍 What was found In an article on Habr, the Just AI team described connecting Claude Code through an API gateway. According to them, Claude Code's agentic mode can work not only with Anthropic models but also with any models available through a compatible gateway. To do this, Claude Code requests are forwarded to an API gateway endpoint, which must be compatible with the Anthropic protocol. The article lists specific models that support the agentic loop and provides connection setup examples — the exact list and configurations are given in the publication itself. ### 💡 Why it matters This approach expands Claude Code's compatibility: instead of proprietary Anthropic models, third-party ones can be used through a single interface. However, not all models support the agentic loop, so the model list helps you pick the right one for the task. The Just AI team shares its experience on its blog, which is especially useful for teams already working with API gateways.
