A key per person and per agent, so you can see the waste and cut it

A raw provider key in a config file has no name on it. Requests go out under an identity nobody can trace, and the invoice arrives as one lump, so nobody can say which team or tool to fix first. With Proxen each person and each agent sends requests with its own key. Every request is tied to one name, and the admin sees counts and costs, not the text.

Coding agents and background services have no seat. They run on a key somebody created once, through the night and through the weekend, and nobody sees the meter until the invoice. AI agent access control means treating an agent like a person: its own key, its own model list, its own monthly budget. The console shows which agent used what and when, and a loop that keeps retrying hits its cap instead of your budget.

When one provider bill lands high, the usual answer is a flat limit for everyone. That freezes the engineers getting the most value and still does not explain the number. Proxen puts a budget on every key and checks it before the request goes out. When a person or agent reaches their monthly cap, their requests stop with a clear message. Everyone else keeps working. The admin can raise the cap, move budget from a quiet key, or leave it until next month.

When someone leaves, a shared password still works for them, and a raw provider key still works for every script it was pasted into. When something leaks, there is no log that says who sent it. Proxen keeps a log per request: which key, which model, how many tokens in and out, what it cost, and when. That is all it keeps by default. Prompt and response text is not stored unless you turn that on. Revoking a person or an agent takes one click and touches nobody else's key.

Without a name on every request, a lower bill could be a quiet month, a price cut or a real saving, and nobody can tell which. With a key per person and per agent, spend shows up by team, tool and model, before and after every change. We agree a baseline with you, then report the saving team by team. Every request runs on your company's own API accounts, so the numbers match your provider invoices.

Here is the whole change. Your company holds its own Anthropic, OpenAI and Google accounts, or we help you open them. Those keys go into Proxen and stay server-side. Each person and each agent gets a Proxen key with a model list, a monthly budget and a hard cap. Engineers change one base URL in Claude Code, Codex, Cursor or their SDK and carry on as before. The proxy cuts the cost of every request, and finance sees the result by person, team and cost center.
