About JustAPI

Better AI economics.
Without a lesser model.

JustAPI gives developers access to leading AI models through one compatible API. You choose the model. We make the underlying compute more cost-efficient.

What we are building

Inference infrastructure that works for the people building with it.

AI products should not have to choose between strong models and sustainable unit economics. We combine demand across customers, purchase capacity at scale and operate dedicated infrastructure so each request can cost less.

The API stays familiar, model selection stays explicit and pricing stays visible before you make the call.

Our principles

Plain where it matters.

Lower prices should come from better infrastructure economics—not hidden compromises.

01

The model stays explicit.

You can see which model you are calling. Lower pricing never needs to mean silently substituting a weaker model.

02

The price is visible.

Input, output and per-request prices are published clearly, including platform fees unless stated otherwise.

03

The integration stays familiar.

An OpenAI-compatible API lets existing applications switch with a new base URL, API key and model ID.

Create your key.
Make your first call.

Open the console, create an API key and start using the model you need in minutes.
