## Status Codes

*   **200 OK:** Request successful. The API call was successful and the response contains the expected data.
*   **400 Bad Request:** Invalid input parameters or malformed request. Check the request body for incorrect data types, missing required fields, or other input errors.
*   **401 Unauthorized:** Missing or invalid API key. Ensure that the `x-api-market-key` header is present and contains a valid API key.
*   **404 Not Found:** Resource not found. The requested endpoint does not exist or the specified resource ID is invalid.
*   **429 Too Many Requests:** Rate limit exceeded. You have exceeded the allowed number of requests within a given time period. See Rate Limits for more information. Implement a retry mechanism with exponential backoff.
*   **500 Internal Server Error:** Server-side error. An unexpected error occurred on the server. If this persists, contact support.
*   **503 Service Unavailable:** Service temporarily unavailable. The service is temporarily down for maintenance or experiencing high load. Try again later.

## Rate Limits

Rate limits are in place to ensure fair usage and prevent abuse. If you exceed the rate limit, you will receive a `429 Too Many Requests` error.

## Error Handling

When an error occurs, the API will return an HTTP error code and a JSON response with error details. The error response will typically include:

*   `error`: A high-level description of the error.
*   `message`: A more detailed message explaining the error.

Example Error Response:

```json
{
  "error": "Invalid input",
  "message": "The 'model' parameter is required."
}
```

Common errors and solutions:

*   `Invalid input`: Check your request parameters and ensure they are valid.
*   `Unauthorized`: Verify that your API key is correct and included in the request header.
*   `Rate limit exceeded`: Implement a retry mechanism with exponential backoff.

## Implementation Guide

This section provides a detailed guide on how to implement and use the ⚡Claude AI | All Models API.

### Example Code

#### JavaScript

```javascript
const apiKey = "YOUR_API_MARKET_KEY";
const baseUrl = "https://prod.api.market/api/v1/magicapi/claude";

async function createChatCompletion(model, 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: model,
        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;
  }
}

// Example usage
async function main() {
  try {
    const model = "claude-sonnet-4-6";
    const messages = [{ role: "user", content: "How many days in 15 weeks" }];
    const completion = await createChatCompletion(model, messages);
    console.log("Completion:", completion);
  } catch (error) {
    console.error("Failed to create chat completion:", error);
  }
}

main();
```

#### Python

```python
import requests

API_KEY = "YOUR_API_MARKET_KEY"
BASE_URL = "https://prod.api.market/api/v1/magicapi/claude"

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

    try:
        response = requests.post(
            f"{BASE_URL}/chat/completions", headers=headers, json=data
        )
        response.raise_for_status()  # Raise HTTPError for bad responses (4xx or 5xx)
        return response.json()
    except requests.exceptions.RequestException as e:
        print(f"API Error: {e}")
        raise

# Example usage
if __name__ == "__main__":
    model = "claude-sonnet-4-6"
    messages = [{"role": "user", "content": "How many days in 15 weeks"}]
    try:
        completion = create_chat_completion(model, messages)
        print("Completion:", completion)
    except Exception as e:
        print(f"Failed to create chat completion: {e}")
```

#### cURL

```bash
curl -X POST "https://prod.api.market/api/v1/magicapi/claude/chat/completions" \
  -H "Content-Type: application/json" \
  -H "x-api-market-key: YOUR_API_MARKET_KEY" \
  -d '{
    "model": "claude-sonnet-4-6",
    "messages": [
      {
        "role": "user",
        "content": "How many days in 15 weeks"
      }
    ]
  }'
```

### Performance Optimization

*   **Choose the right model:** Select the most appropriate Claude model for your specific use case to balance performance and cost.
*   **Optimize input:** Ensure your input data is well-formatted and relevant to the task.  This will improve response quality.
