# List Models

> Retrieve the complete catalog of AI models

## Overview

Retrieve the complete catalog of AI models available through Concentrate AI. This endpoint returns all models with their provider configurations, pricing, capabilities, and technical specifications.

## Authentication

<Info>
  This endpoint **does not require** authentication. You can call it without an API key.
</Info>

## Filter Query Parameters

You can filter results using dot-notation query parameters. All filters are ANDed together.

### Equality Filters

Filter on any field using dot-notation paths:

```
GET /v1/models?author.slug=anthropic
GET /v1/models?supports.streaming=true
GET /v1/models?supports.tools.function_calling=true
GET /v1/models?integrations.claude_code.details.compatibility=high
```

### Numeric Comparison Operators

Append `.gte`, `.lte`, `.gt`, or `.lt` to any numeric field path:

```
GET /v1/models?context_window.gte=128000
GET /v1/models?max_output_tokens.lte=8192
GET /v1/models?pricing.tokens.input.price.USD.lt=0.01
```

### Provider-level vs Model-level Paths

* **Provider-level** (`supports.*`, `context_window`, `max_output_tokens`, `pricing.*`, `image_processing.*`): a model matches if **any** of its providers match the filter.
* **Model-level** (`slug`, `name`, `author.*`, `integrations.*`): resolved directly on the model object.

### Combining Filters

Multiple filters are ANDed together:

```
GET /v1/models?author.slug=anthropic&supports.streaming=true&context_window.gte=128000
```
