      ```bash cURL theme={null}
      curl https://api.heyaskr.ai/chat/completions \
        -H "Authorization: Bearer ASKR_API_KEY" \
        -H "Content-Type: application/json" \
        -d '{
          "model": "gpt-5.5",
          "messages": [{"role": "user", "content": "Say hello to Askr."}]
        }'
      ```

      ```python Python theme={null}
      from openai import OpenAI

      client = OpenAI(base_url="https://api.heyaskr.ai", api_key="ASKR_API_KEY")

      resp = client.chat.completions.create(
          model="gpt-5.5",
          messages=[{"role": "user", "content": "Say hello to Askr."}],
      )
      print(resp.choices[0].message.content)
      ```

      ```javascript Node theme={null}
      import OpenAI from "openai";

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

      const resp = await client.chat.completions.create({
        model: "gpt-5.5",
        messages: [{ role: "user", content: "Say hello to Askr." }],
      });
      console.log(resp.choices[0].message.content);

    "model": "claude-sonnet-4.6"   # Anthropic
    "model": "gemini-2.5-pro"      # Google
    "model": "deepseek-chat"       # DeepSeek
