Scalaix
AI API infrastructure

Build AI APIs,
not model integrations.

Turn any AI capability into a stable, versioned API. Define what it should do, test it across models, and deploy an endpoint your application can rely on.

Models change. Your API doesn't.

From idea to endpoint

Describe the capability.
Scalaix builds the API.

Tell Scalaix what you need in plain English. It creates the inputs, instructions and structured output, then lets you test the same contract across models.

What should your API do?
Accept a support ticket and screenshot. Categorize the issue, determine its priority, and return a suggested response.
1

Describe

Plain English → inputs, instructions and output schema

2

Compare

Run the same task across multiple models

3

Deploy

Publish a stable, versioned endpoint

Model independent

One API. Pick the model that works.

Run the same inputs and output contract against different models. Compare results, then switch the model underneath without changing your application.

Infrastructure primitives

Everything between your application and the model.

Keep AI orchestration out of application code and behind a stable API contract.

1

Stable API contracts

Define inputs and structured outputs once.

2

Model switching

Change models without changing application code.

3

API versioning

Ship changes without breaking existing integrations.

4

Automatic fallbacks

Keep running when a provider fails or slows down.

Expanding capability
5

Caching

Avoid repeated model calls and unnecessary cost.

Expanding capability
6

Visual workflows

Make prompts, models and decision logic visible and testable.

Expanding capability
Templates

Start with an API, not a blank page.

Use a template as-is or change the inputs, model, instructions and output contract.

Build against an API.
Not a model.

Create stable AI endpoints that can evolve as models do.
