One model. Two prices.
Shown with pack credits at that pack’s price per credit. Bigger packs make every model cheaper.
The demands wall.
Everything people kept asking for. All of it is just how ZOLT works.
Why ZOLT
One key, one balance, every model. ZOLT handles the routing, the failover, and the metering, so your apps just work.
Automatic failover
If a connection drops in the middle of an answer, ZOLT moves your call to a healthy one on its own. Your app just sees one steady stream.
Per-credit metering
Every call is charged per token at that model’s own credit rate. No flat fees, no rounding up, no minimum charge.
Hard spend caps
Every key carries a built-in ceiling tied to the credits it was sold. A key stops itself before it can ever overspend.
One key, every app
The same key works in the ZOLT widget, the setup app, the CLI, and any OpenAI-compatible tool you already use.
Your app sends a normal OpenAI-format call to one base URL.
ZOLT picks the fastest healthy route for that model.
The answer streams back. If anything drops, a backup route takes over without breaking the stream.
Pay once. Credits stay.
Buy on the Pricing page. Credits never expire, and top-ups land on the same key.
Fair questions.
ZOLT is one prepaid key for many AI models. You buy credits once, point your app at our base URL, and every call is charged per token in credits at that model’s own rate.
Pick a pack on the Pricing page and pay the QR with GCash, Maya, or your bank app. Then type your payment number on the same page and your key appears there.
Pack credits never expire. Passes are different: a pass adds 200 credits every morning, and those daily credits are for that day.
Any app that takes an OpenAI-style base URL and API key. Set the base URL to https://api.zoltllm.com/v1 and paste your key. The Sign in page shows your balance any time.
Use the Already paid box on the payment page with the Ref. No. from a GCash receipt, or the Trace ID or Invoice No. from other apps. If it still does not show, tap the chat bubble and talk to a person.
