⚠ Match your group. Your key only works with the model / group it was purchased for. After setup, pick that model inside Codex or Claude Code — if you choose a model your key does not cover, it will not work (you may see “model not found”, 401, or 404 errors). All purchased keys are non-refundable — double-check before you buy.
The key you received after purchase. It starts with sk-gos- — only letters, numbers and dashes are accepted.
All keys target api.gratobeun.com and every request is carried through the VPS Proxy (45.32.100.117) — your IP is masked. Both are baked into your config automatically.

ℹ These files default to gpt-5.5. Pick whichever model your key's group supports from inside the Codex extension — it switches models directly. To change the startup default, edit the model / review_model lines in config.toml.

        ℹ
        This file points Claude Code at the Gratobeun Gateway. Pick whichever model your key's group supports from inside Claude Code — it switches models directly. Claude Code needs a Claude-tier key; if your key isn't for a Claude group the gateway returns a clean error (non-Claude keys won't work here).
      


      
Your config starts on claude-sonnet-5 (balanced speed & cost, so keys don't burn credits by default). The /model picker inside Claude Code only shows the models your gateway covers — switch anytime from the CLI.
