## API Documentation

### Base URL

All API requests should be made to: `https://prod.api.market/api/v1/magicapi/gpt-5-nano`

### Authentication

Include your API key in the request header:

```
x-api-market-key: YOUR_API_MARKET_KEY
```

### Asynchronous Processing

**IMPORTANT**: This API uses asynchronous processing.

1.  Submit a prediction request to the POST endpoint.
2.  Receive a prediction ID in the response.
3.  Poll the GET endpoint with the prediction ID to check status: `GET /api/v1/magicapi/gpt-5-nano/predictions/{id}`
4.  Continue polling until the prediction is complete.

Recommended implementation details:

*   Polling interval: 1 second
*   Maximum timeout: 600 seconds (10 minutes)
*   Handle statuses: "starting", "processing", "succeeded", "failed"

### Endpoints

#### Create Chat Completion

`POST /api/v1/magicapi/gpt-5-nano/chat/completions`

Creates a model response for a given chat conversation.

```bash
curl -X POST "https://prod.api.market/api/v1/magicapi/gpt-5-nano/chat/completions" \
-H "Content-Type: application/json" \
-H "x-api-market-key: YOUR_API_MARKET_KEY" \
-d '{
  "model": "gpt-5-nano",
  "messages": [
    {"role": "user", "content": "There are ten birds in a tree. A hunter shoots one. How many are left in the tree?"}
  ]
}'
```

```json
{
  "id": "chatcmpl-CFJWVPlCose16sy2GzKWGeowqva9s",
  "object": "chat.completion",
  "created": 1757766003,
  "model": "gpt-5-nano",
  "choices": [
    {
      "index": 0,
      "finish_reason": "stop",
      "message": {
        "role": "assistant",
        "content": "If a hunter shoots one bird, the noise would likely scare the other birds away. So, even though one bird is shot, the rest would typically fly off, leaving **0 birds** in the tree."
      }
    }
  ],
  "usage": {
    "prompt_tokens": 28,
    "completion_tokens": 43,
    "total_tokens": 71
  }
}
```



## Status Codes

*   200 OK: Request successful.
*   201 Created (for asynchronous operations):  The request has been accepted for processing, but the processing has not been completed.
*   400 Bad Request: Invalid input parameters or malformed request.
*   401 Unauthorized: Missing or invalid API key.
*   403 Forbidden: Valid API key but insufficient permissions.
*   404 Not Found: Resource not found.
*   429 Too Many Requests: Rate limit exceeded.
*   500 Internal Server Error: Server-side error.
*   503 Service Unavailable: Service temporarily unavailable.


## Error Handling

Error responses are provided in JSON format:

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