Your AI key can leak. Your bill can't.
Sluiceline is an AI key gateway — point your AI agent or SaaS at a quota-capped safe-key. The real provider key never leaves the server, and requests stop at the cap you set.

ByteDanceEverything your AI key needs once it's out there
The primitives you would otherwise have to build yourself.
Safe-key hosting
Your real AI provider key is encrypted with AES-256-GCM and stays server-side. Requests are forwarded through a safe-key instead, so the real key never reaches your code or the client.
Seamless switch
Replace your AI provider's base URL and key with the gateway's URL and a safe-key — two values in your config, no code changes.
UV / PV quotas
Three quotas — requests (PV), distinct visitors per day, and calls per visitor. A visitor who spends the day's allowance is stopped.
Mock mode
Return preset responses instead of real calls during testing and demos — zero cost, no provider quota spent.
One-click pause / resume
Pause any safe-key the moment traffic looks wrong; resume it with the configuration intact.
Usage console & alerts
Each key's usage against its quotas, plus the time, reason, IP and user agent behind every blocked request — with threshold alert emails on paid plans.
Two lines change
The request, the body and the response stay the provider's own; only the base URL and the credential differ.

One-time setup, three steps.
Host your real key
Create an account and give us your AI provider's real key; we store it encrypted.
Get your safe-key
We issue a safe-key and give you the base URL your app calls instead.
Swap two values
Point your SDK's base URL at the gateway and use the safe-key as the credential.
Plans for every product count
Start free, and move up when you need more keys or more PV per day.
Your key can leak. Your bill stays capped.
Create a safe-key, set its quota, use it in place of the real key — no code changes, done in minutes.
