Sell Claude API keys on your own terms

Issue sub keys from your official Claude API account. Decide each key's rate limit, spend limit and credit balance — and the keys work straight inside the official Claude SDK and apps.

Rate limits

Per-minute request caps and a daily request quota on every key.

Spend limits

Hard dollar ceiling per key — the proxy stops the key at the cap.

Credits

Give each customer a credit balance; usage burns it down in real time.

Instant control

Disable, expire, reset or delete any key the moment you need to.
