One gateway on your host for your model accounts: Claude, Codex and Gemini subscriptions and an Anthropic API key. Calls go to the subscriptions first and to the API key last, and return to the subscriptions after their limits reset.
Each tool gets its own key with its own models and daily limits. CLIs, copilots and Nous use it the same way, and a CLI pane can move to it when its direct account reaches its usage limit.
Token usage and your bill#
Every token is counted once, per model, provider and account, with its API value at list prices: the gateway's own request logs plus the CLI calls that did not go through it. With your Anthropic Admin key, the gateway reads Anthropic's real bill every few minutes and shows today, 7 days, this month and 31 days next to your monthly budget and the credits you entered.
