## Start in minutes

ZnapAI is compatible with the OpenAI SDK — change only `base_url` and `api_key`:

<CodeGroup>
  ```bash cURL theme={null}
  curl --location 'https://api.znapai.com/v1/chat/completions' \
  --header 'Content-Type: application/json' \
  --header 'Authorization: Bearer $ZnapAI_API_KEY' \
  --data '{
      "model": "gpt-4o-mini",
      "messages": [
        {
          "role": "user",
          "content": "Hello!"
        }
      ]
    }'
  ```

  ```python OpenAI SDK (Python) theme={null}
  import os
  import openai

  client = openai.OpenAI(
      api_key=os.environ["ZnapAI_API_KEY"],
      base_url="https://api.znapai.com/v1"
  )

  response = client.chat.completions.create(
      model="gpt-4o-mini",
      messages=[{"role": "user", "content": "Hello!"}]
  )
  print(response.choices[0].message.content)
  ```

  ```typescript OpenAI SDK (JS) theme={null}
  import OpenAI from "openai";

  const client = new OpenAI({
    apiKey: process.env.ZnapAI_API_KEY,
    baseURL: "https://api.znapai.com/v1",
  });

  const response = await client.chat.completions.create({
    model: "gpt-4o-mini",
    messages: [{ role: "user", content: "Hello!" }],
  });
  console.log(response.choices[0].message.content);
  ```
</CodeGroup>

<Tip>
  Already using the OpenAI SDK? Only `base_url` and `api_key` need to change — your existing application code works without modification.
