    "model": "gpt-5.2",
    "stream": false,
    "messages": [

## Status Codes

*   200 OK: Request successful.
*   400 Bad Request: Invalid input parameters or malformed request. Review the request body and ensure all required fields are present and correctly formatted.
*   401 Unauthorized: Missing or invalid API key. Provide a valid API key in the `x-api-market-key` header.
*   500 Internal Server Error: Server-side error. This indicates an issue on our end. Please try again later. If the problem persists, contact support.


## Error Handling

The API returns error responses in JSON format with a clear error code and message.

```json
{
  "error": {
    "code": "invalid_parameter",
    "message": "The 'model' parameter is required.",
    "status": 400
  }
}
```

Common errors and how to resolve them:

*   `invalid_parameter`: A required parameter is missing or invalid. Check the request body against the API documentation and ensure all parameters are present and of the correct type.
*   `unauthorized`: The API key is missing or invalid. Ensure a valid API key is included in the `x-api-market-key` header.

For transient errors (e.g., 500 Internal Server Error), implement a retry strategy with exponential backoff.

## Implementation Guide

### Example Code

```javascript
// JavaScript example with proper polling and timeout
const apiKey = "YOUR_API_MARKET_KEY";
const baseUrl = "https://prod.api.market/api/v1/magicapi/gpt-5-2";

async function createChatCompletion(messages) {
  try {
    const response = await fetch(`${baseUrl}/chat/completions`, {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
        "x-api-market-key": apiKey
      },
      body: JSON.stringify({ model: "gpt-5.2", messages: messages })
    });

    if (!response.ok) {
      throw new Error(`API error: ${response.status} ${response.statusText}`);
    }

    const data = await response.json();
    return data;
  } catch (error) {
    console.error("Error:", error);
    throw error;
  }
}

async function main() {
  const messages = [{ role: "user", content: "Write a javascript hello world function." }];
  try {
    const completion = await createChatCompletion(messages);
    console.log("Completion:", completion.choices[0].message.content);
  } catch (error) {
    console.error("Failed to get completion:", error);
  }
}

main();
```

```python
# Python example
import requests

API_KEY = "YOUR_API_MARKET_KEY"
BASE_URL = "https://prod.api.market/api/v1/magicapi/gpt-5-2"

def create_chat_completion(messages):
    headers = {
        "Content-Type": "application/json",
        "x-api-market-key": API_KEY
    }

    data = {
        "model": "gpt-5.2",
        "messages": messages
    }

    response = requests.post(f"{BASE_URL}/chat/completions", headers=headers, json=data)

    if response.status_code != 200:
        raise Exception(f"API error: {response.status_code} - {response.text}")

    return response.json()

def main():
    messages = [{"role": "user", "content": "Write a python hello world function."}]
    try:
        completion = create_chat_completion(messages)
        print("Completion:", completion['choices'][0]['message']['content'])
    except Exception as e:
        print(f"Failed to get completion: {e}")

if __name__ == "__main__":
    main()
```

```bash
# cURL example
curl -X POST "https://prod.api.market/api/v1/magicapi/gpt-5-2/chat/completions" \
  -H "Content-Type: application/json" \
  -H "x-api-market-key: YOUR_API_MARKET_KEY" \
  -d '{
    "model": "gpt-5.2",
    "messages": [
      {
        "role": "user",
        "content": "Write a bash script that lists all files in the current directory."
      }
    ]
  }'
