Hard Stop

AI API costs can get out of control.

Shared master keys

You shouldn’t hand out your OpenAI key to every agent or teammate.

No hard stop

A loop or runaway agent can keep calling the API until the bill hurts.

Weak control

Limits and allowlists should be enforced — not just reported after the fact.

How it works

No custom SDK required. Use your existing OpenAI client with a different base URL.

  1. 01

    Connect

    Bind your OpenAI API key. It is encrypted at rest.

  2. 02

    Create

    Issue a virtual key with daily/monthly limits, model allowlist, and concurrency.

  3. 03

    Use

    Send OpenAI-compatible requests to KeyGood with the virtual key.
