# Endpoints

X6.AI has one endpoint: `https://api.x6.ai`. The account, API key, request paths, model list, and billing all use this host.

**The endpoint host does not include `/v1`.** Add `/v1` only on concrete API paths (e.g. `/v1/chat/completions`) or in the OpenAI SDK `base_url`.

## OpenAI SDK

OpenAI SDK `base_url` must append `/v1` to the endpoint host:

```python
from openai import OpenAI

client = OpenAI(
    base_url="https://api.x6.ai/v1",
    api_key="your-api-key",
)
```

## Anthropic SDK

Anthropic SDK `base_url` is the endpoint host (**no** `/v1`):

```python
import anthropic

client = anthropic.Anthropic(
    api_key="sk-snx-...",
    base_url="https://api.x6.ai",
)
```
