    headers={
        "X-DeepSeek-API-Token": "<YOUR_DEEPSEEK_API_KEY>",
        "X-Anthropic-API-Token": "<YOUR_ANTHROPIC_API_KEY>"
    },
    json={
        "messages": [
            {"role": "user", "content": "How many 'r's in the word 'strawberry'?"}
        ]
    }
)

print(response.json())
```

Example JSON structure for configuring API requests, including stream, verbose, system prompts, messages, and provider-specific configurations.

```json
{
    "stream": false,
    "verbose": false,
    "system": "Optional system prompt",
    "messages": [...],
    "deepseek_config": {
        "headers": {},
        "body": {}
    },
    "anthropic_config": {
        "headers": {},

    }
}
```

--------------------------------

### cURL Example: Missing DeepSeek API Key

Source: https://context7.com/winfunc/deepreasoning/llms.txt

Demonstrates how to make a POST request using cURL and the expected error response when the 'X-DeepSeek-API-Token' header is missing.

```bash
# Missing DeepSeek token:
curl -X POST http://127.0.0.1:1337/ \
  -H "Content-Type: application/json" \
  -H "X-Anthropic-API-Token: YOUR_ANTHROPIC_KEY" \
  -d '{"messages": [{"role": "user", "content": "Hello"}]}'

# Response (HTTP 400):
# {
#   "error": {
#     "message": "Missing required header: X-DeepSeek-API-Token",
#     "type": "missing_header",
#     "param": "X-DeepSeek-API-Token"
#   }
# }

```

--------------------------------

### Python Streaming Example

Source: https://github.com/winfunc/deepreasoning/blob/main/README.md

Demonstrates how to stream responses from the API using Python's httpx library. Ensure you have your DeepSeek and Anthropic API keys configured.

```python
import asyncio
import json
import httpx

async def stream_response():
    async with httpx.AsyncClient() as client:
        async with client.stream(
            "POST",
            "http://127.0.0.1:1337/",
            headers={
                "X-DeepSeek-API-Token": "<YOUR_DEEPSEEK_API_KEY>",
                "X-Anthropic-API-Token": "<YOUR_ANTHROPIC_API_KEY>"
            },
            json={
                "stream": True,
                "messages": [
                    {"role": "user", "content": "How many 'r's in the word 'strawberry'?"}
                ]
            }
        ) as response:
            response.raise_for_status()
            async for line in response.aiter_lines():
                if line:
                    if line.startswith('data: '):
                        data = line[6:]
                        try:
                            parsed_data = json.loads(data)
                            if 'content' in parsed_data:
                                content = parsed_data.get('content', '')[0]['text']
                                print(content, end='',flush=True)
                            else:
                                print(data, flush=True)
                        except json.JSONDecodeError:
                            pass

if __name__ == "__main__":
    asyncio.run(stream_response())
```

--------------------------------

### cURL Example: Duplicate System Prompt

Source: https://context7.com/winfunc/deepreasoning/llms.txt

Illustrates a cURL request that triggers an HTTP 400 error due to providing a system prompt in both the root level and the messages array. Shows the expected error response.

```bash
# Duplicate system prompt (both root-level and in messages array):
curl -X POST http://127.0.0.1:1337/ \
  -H "Content-Type: application/json" \
  -H "X-DeepSeek-API-Token: KEY" \
  -H "X-Anthropic-API-Token: KEY" \
  -d '{
    "system": "Be helpful.",
    "messages": [
      {"role": "system", "content": "Be concise."},
      {"role": "user", "content": "Hi"}
    ]
  }'

# Response (HTTP 400):
# {
#   "error": {
#     "message": "System prompt can only be provided once, either in root or messages array",
#     "type": "invalid_system_prompt"
#   }
# }

```

### Chat Completion (Streaming via SSE)

Source: https://context7.com/winfunc/deepreasoning/llms.txt

This endpoint enables chat completions with streaming support using Server-Sent Events (SSE). By setting `"stream": true`, the API returns events like `start`, `content`, `usage`, `done`, and `error`.

```APIDOC
## POST / — Chat Completion (Streaming via SSE)

### Description
Setting `"stream": true` switches the endpoint to Server-Sent Events mode. The stream emits a `start` event, then a series of `content` events (first streaming the DeepSeek reasoning deltas inside `<thinking>` tags, then Claude's response deltas), followed by a `usage` event with final token counts and costs, and a terminal `done` event. Errors during streaming are delivered as `error` events.

### Method
POST

### Endpoint
/

### Parameters
#### Query Parameters
- **stream** (boolean) - Optional - If true, enables Server-Sent Events streaming.

#### Request Body
- **stream** (boolean) - Required - Enables or disables streaming.
- **verbose** (boolean) - Optional - If true, includes raw upstream API responses for debugging.
- **system** (string) - Optional - A system prompt to guide the AI's behavior. Mutually exclusive with a system role in `messages`.
- **messages** (array) - Required - An array of message objects, each with a `role` (user, assistant, or system) and `content`.
- **deepseek_config** (object) - Optional - Configuration for the DeepSeek provider.
  - **headers** (object) - Optional - Custom headers for the DeepSeek request.
  - **body** (object) - Optional - Request body parameters for DeepSeek.
    - **model** (string) - Optional - The DeepSeek model to use (e.g., `deepseek-reasoner`).
    - **max_tokens** (integer) - Optional - The maximum number of tokens to generate.
    - **temperature** (number) - Optional - Controls randomness. Higher values mean more random output.
- **anthropic_config** (object) - Optional - Configuration for the Anthropic provider.
  - **headers** (object) - Optional - Custom headers for the Anthropic request.
  - **body** (object) - Optional - Request body parameters for Anthropic.
    - **model** (string) - Optional - The Anthropic model to use (e.g., `claude-3-5-sonnet-20241022`).
    - **max_tokens** (integer) - Optional - The maximum number of tokens to generate.

### Request Example
```json
{
  "stream": true,
  "messages": [
    {"role": "user", "content": "Write a Python quicksort implementation."}
  ],
  "deepseek_config": {
    "headers": {
      "X-DeepSeek-API-Token": "YOUR_DEEPSEEK_KEY"
    }
  },
  "anthropic_config": {
    "headers": {
      "X-Anthropic-API-Token": "YOUR_ANTHROPIC_KEY"
    }
  }
}
```

### Response
#### Success Response (SSE Stream)
Events are streamed as Server-Sent Events. Each event is prefixed with `event: <type>` and `data: <json_payload>`.

- **start**: Indicates the stream has started. Contains a `created` timestamp.
- **content**: Contains streaming deltas. `content` is an array of blocks, each with `text` (full block) and `text_delta` (incremental chunk).
- **usage**: Contains final token counts and costs for each provider.
- **done**: Indicates the stream has completed.
- **error**: If an error occurs during streaming, this event provides error details.

#### Example SSE Event (`content`)
```
event: content
data: {"type": "content", "content": [{"type": "text", "text": "def quicksort(arr):\n    if len(arr) <= 1:\n        return arr\n    pivot = arr[len(arr) // 2]\n    left = [x for x in arr if x < pivot]\n    middle = [x for x in arr if x == pivot]\n    right = [x for x in arr if x > pivot]\n    return quicksort(left) + middle + quicksort(right)\n"}]}
```

### Error Responses
All errors return a JSON body with an `error` object containing `message`, `type`, and optional `param` and `code` fields.

- **HTTP 400**: `missing_header` (e.g., missing API key), `invalid_system_prompt` (e.g., duplicate system prompts).
- **Upstream API Failures**: `deepseek_*` or `anthropic_*` types.
- **HTTP 500**: `internal_error` for internal server issues.
