# Models

Retrieve the list of models currently available on the DOS AI platform. This endpoint is useful for dynamically discovering which models you can use without hard-coding model IDs.

## Endpoint

```
GET https://api.dos.ai/v1/models
```

## Authentication

Include your API key in the `Authorization` header:

```
Authorization: Bearer dos_sk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
```

## Request

No request body or query parameters are required.

## Response

### Success (200 OK)

```json
{
  "object": "list",
  "data": [
    {
      "id": "dos-ai",
      "object": "model",
      "created": 1711000000,
      "owned_by": "dos-ai"
    },
    {
      "id": "llama-3.3-70b",
      "object": "model",
      "created": 1711000000,
      "owned_by": "dos-ai"
    },
    {
      "id": "deepseek-v3",
      "object": "model",
      "created": 1711000000,
      "owned_by": "dos-ai"
    },
    {
      "id": "llama-3.1-8b",
      "object": "model",
      "created": 1711000000,
      "owned_by": "dos-ai"
    }
  ]
}
```

## Examples

### cURL

```bash
curl https://api.dos.ai/v1/models \
  -H "Authorization: Bearer dos_sk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
```

### Python

```python
from openai import OpenAI

client = OpenAI(
    api_key="dos_sk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    base_url="https://api.dos.ai/v1"
)

models = client.models.list()
for model in models.data:
    print(model.id)
```

### Node.js

```javascript
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "dos_sk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  baseURL: "https://api.dos.ai/v1",
});

const models = await client.models.list();
for (const model of models.data) {
  console.log(model.id);
}
```

> **Note:** The list of available models may change over time as new models are added. We recommend fetching the model list dynamically rather than hard-coding model IDs in your application.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.dos.ai/api-reference/models.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
