## OpenAI-Compatible API

### Create chat completion

**POST** `/api/v1/chats_openai/{chat_id}/chat/completions`

Creates a model response for a given chat conversation.

This API follows the same request and response format as OpenAI's API. It allows you to interact with the model in a manner similar to how you would with [OpenAI's API](https://platform.openai.com/docs/api-reference/chat/create).

#### Request

- Method: POST
- URL: `/api/v1/chats_openai/{chat_id}/chat/completions`
- Headers:
  - `'content-Type: application/json'`
  - `'Authorization: Bearer <YOUR_API_KEY>'`
- Body:
  - `"model"`: `string`
  - `"messages"`: `object list`
  - `"stream"`: `boolean`
  - `"extra_body"`: `object` (optional)

##### Request example

```bash
curl --request POST \
     --url http://{address}/api/v1/chats_openai/{chat_id}/chat/completions \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data '{
        "model": "model",
        "messages": [{"role": "user", "content": "Say this is a test!"}],
        "stream": true,
        "extra_body": {
          "reference": true,
          "metadata_condition": {
            "logic": "and",
            "conditions": [
              {
                "name": "author",
                "comparison_operator": "is",
                "value": "bob"
              }
            ]
          }
        }
      }'
```

##### Request Parameters

- `model` (*Body parameter*) `string`, *Required*  
  The model used to generate the response. The server will parse this automatically, so you can set it to any value for now.

- `messages` (*Body parameter*) `list[object]`, *Required*  
  A list of historical chat messages used to generate the response. This must contain at least one message with the `user` role.

- `stream` (*Body parameter*) `boolean`  
  Whether to receive the response as a stream. Set this to `false` explicitly if you prefer to receive the entire response in one go instead of as a stream.

- `extra_body` (*Body parameter*) `object`  
  Extra request parameters:  
  - `reference`: `boolean` - include reference in the final chunk (stream) or in the final message (non-stream).
  - `metadata_condition`: `object` - metadata filter conditions applied to retrieval results.

  - Must not be included when `"chunk_method"` is specified.

:::caution WARNING
You can choose either of the following ingestion options when creating a dataset, but *not* both:

- Use a built-in chunk method -- specify `"chunk_method"` (optionally with `"parser_config"`).
- Use an ingestion pipeline -- specify both `"parse_type"` and `"pipeline_id"`.

If none of `"chunk_method"`, `"parse_type"`, or `"pipeline_id"` are provided, the system defaults to `chunk_method = "naive"`.

## CHAT ASSISTANT MANAGEMENT

### Create chat assistant

**POST** `/api/v1/chats`

Creates a chat assistant.

#### Request

- Method: POST
- URL: `/api/v1/chats`
- Headers:
  - `'content-Type: application/json'`
  - `'Authorization: Bearer <YOUR_API_KEY>'`
- Body:
  - `"name"`: `string`
  - `"avatar"`: `string`
  - `"dataset_ids"`: `list[string]`
  - `"llm"`: `object`
  - `"prompt"`: `object`

##### Request example

```shell
curl --request POST \
     --url http://{address}/api/v1/chats \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data '{
    "dataset_ids": ["0b2cbc8c877f11ef89070242ac120005"],
    "name":"new_chat_1"
}'
```

##### Request parameters

- `"name"`: (*Body parameter*), `string`, *Required*  
  The name of the chat assistant.
- `"avatar"`: (*Body parameter*), `string`  
  Base64 encoding of the avatar.
- `"dataset_ids"`: (*Body parameter*), `list[string]`  
  The IDs of the associated datasets.
- `"llm"`: (*Body parameter*), `object`  
  The LLM settings for the chat assistant to create. If it is not explicitly set, a JSON object with the following values will be generated as the default. An `llm` JSON object contains the following attributes:  
  - `"model_name"`, `string`  
    The chat model name. If not set, the user's default chat model will be used.  

  :::caution WARNING
  `model_type` is an *internal* parameter, serving solely as a temporary workaround for the current model-configuration design limitations.

  Its main purpose is to let *multimodal* models (stored in the database as `"image2text"`) pass backend validation/dispatching. Be mindful that:

  - Do *not* treat it as a stable public API.
  - It is subject to change or removal in future releases.
  :::

  - `"model_type"`: `string`  
    A model type specifier. Only `"chat"` and `"image2text"` are recognized; any other inputs, or when omitted, are treated as `"chat"`.
  - `"model_name"`, `string`
  - `"temperature"`: `float`  
    Controls the randomness of the model's predictions. A lower temperature results in more conservative responses, while a higher temperature yields more creative and diverse responses. Defaults to `0.1`.  
  - `"top_p"`: `float`  
    Also known as “nucleus sampling”, this parameter sets a threshold to select a smaller set of words to sample from. It focuses on the most likely words, cutting off the less probable ones. Defaults to `0.3`  
  - `"presence_penalty"`: `float`  
    This discourages the model from repeating the same information by penalizing words that have already appeared in the conversation. Defaults to `0.4`.
  - `"frequency penalty"`: `float`  
    Similar to the presence penalty, this reduces the model’s tendency to repeat the same words frequently. Defaults to `0.7`.
- `"prompt"`: (*Body parameter*), `object`  
  Instructions for the LLM to follow. If it is not explicitly set, a JSON object with the following values will be generated as the default. A `prompt` JSON object contains the following attributes:  
  - `"similarity_threshold"`: `float` RAGFlow employs either a combination of weighted keyword similarity and weighted vector cosine similarity, or a combination of weighted keyword similarity and weighted reranking score during retrieval. This argument sets the threshold for similarities between the user query and chunks. If a similarity score falls below this threshold, the corresponding chunk will be excluded from the results. The default value is `0.2`.
  - `"keywords_similarity_weight"`: `float` This argument sets the weight of keyword similarity in the hybrid similarity score with vector cosine similarity or reranking model similarity. By adjusting this weight, you can control the influence of keyword similarity in relation to other similarity measures. The default value is `0.7`.
  - `"top_n"`: `int` This argument specifies the number of top chunks with similarity scores above the `similarity_threshold` that are fed to the LLM. The LLM will *only* access these 'top N' chunks.  The default value is `6`.
  - `"variables"`: `object[]` This argument lists the variables to use in the 'System' field of **Chat Configurations**. Note that:  
    - `"knowledge"` is a reserved variable, which represents the retrieved chunks.
    - All the variables in 'System' should be curly bracketed.
    - The default value is `[{"key": "knowledge", "optional": true}]`.
  - `"rerank_model"`: `string` If it is not specified, vector cosine similarity will be used; otherwise, reranking score will be used.
  - `top_k`: `int` Refers to the process of reordering or selecting the top-k items from a list or set based on a specific ranking criterion. Default to 1024.
  - `"empty_response"`: `string` If nothing is retrieved in the dataset for the user's question, this will be used as the response. To allow the LLM to improvise when nothing is found, leave this blank.
  - `"opener"`: `string` The opening greeting for the user. Defaults to `"Hi! I am your assistant, can I help you?"`.
  - `"show_quote`: `boolean` Indicates whether the source of text should be displayed. Defaults to `true`.
  - `"prompt"`: `string` The prompt content.

### Converse with agent

**POST** `/api/v1/agents/{agent_id}/completions`  

Asks a specified agent a question to start an AI-powered conversation.

:::tip NOTE

- In streaming mode, not all responses include a reference, as this depends on the system's judgement.
- In streaming mode, the last message is an empty message:

  ```
  [DONE]
  ```

- You can optionally return step-by-step trace logs (see `return_trace` below).

:::

#### Request

- Method: POST
- URL: `/api/v1/agents/{agent_id}/completions`
- Headers:
  - `'content-Type: application/json'`
  - `'Authorization: Bearer <YOUR_API_KEY>'`
- Body:
  - `"question"`: `string`
  - `"stream"`: `boolean`
  - `"session_id"`: `string` (optional)
  - `"inputs"`: `object` (optional)
  - `"user_id"`: `string` (optional)
  - `"return_trace"`: `boolean` (optional, default `false`) — include execution trace logs.

#### Streaming events to handle

When `stream=true`, the server sends Server-Sent Events (SSE). Clients should handle these `event` types:

- `message`: streaming content from Message components.
- `message_end`: end of a Message component; may include `reference`/`attachment`.
- `node_finished`: a component finishes; `data.inputs/outputs/error/elapsed_time` describe the node result. If `return_trace=true`, the trace is attached inside the same `node_finished` event (`data.trace`).

The stream terminates with `[DONE]`.

:::info IMPORTANT
You can include custom parameters in the request body, but first ensure they are defined in the [Begin](../guides/agent/agent_component_reference/begin.mdx) component.
:::

##### Request example

- If the **Begin** component does not take parameters:

```bash
curl --request POST \
     --url http://{address}/api/v1/agents/{agent_id}/completions \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data-binary '
     {
        "question": "Hello",
        "stream": false,
     }'
```

- If the **Begin** component takes parameters, include their values in the body of `"inputs"` as follows:  

```bash
curl --request POST \
     --url http://{address}/api/v1/agents/{agent_id}/completions \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data-binary '
    {
        "question": "Hello",
        "stream": false,
        "inputs": {
            "line_var": {
                "type": "line",
                "value": "I am line_var"
            },
            "int_var": {
                "type": "integer",
                "value": 1
            },
            "paragraph_var": {
                "type": "paragraph",
                "value": "a\nb\nc"
            },
            "option_var": {
                "type": "options",
                "value": "option 2"
            },
            "boolean_var": {
                "type": "boolean",
                "value": true
            }
        }
    }'
```

The following code will execute the completion process

```bash
curl --request POST \
     --url http://{address}/api/v1/agents/{agent_id}/completions \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data-binary '
     {
          "question": "Hello",
          "stream": true,
          "session_id": "cb2f385cb86211efa36e0242ac120005"
     }'
```

##### Request Parameters

- `agent_id`: (*Path parameter*), `string`  
  The ID of the associated agent.
- `"question"`: (*Body Parameter*), `string`, *Required*  
  The question to start an AI-powered conversation.
- `"stream"`: (*Body Parameter*), `boolean`  
  Indicates whether to output responses in a streaming way:  
  - `true`: Enable streaming (default).
  - `false`: Disable streaming.
- `"session_id"`: (*Body Parameter*)  
  The ID of the session. If it is not provided, a new session will be generated.
- `"inputs"`: (*Body Parameter*)  
  Variables specified in the **Begin** component.  
- `"user_id"`: (*Body parameter*), `string`  
  The optional user-defined ID. Valid *only* when no `session_id` is provided.

:::tip NOTE
For now, this method does *not* support a file type input/variable. As a workaround, use the following to upload a file to an agent:  
`http://{address}/v1/canvas/upload/{agent_id}`  
*You will get a corresponding file ID from its response body.*
:::

#### Response

success without `session_id` provided and with no variables specified in the **Begin** component:

This is a fundamental question about personal identity.\n\n2. **Decompose the Request**: The request is quite simple and doesn't require complex decomposition. The core task is to provide an answer that identifies the user in some capacity.\n\n3. **Execute the Subtask**:\n   - **Identify the nature of the question**: The user is seeking to understand their own existence or their sense of self.\n   - **Assess the context**: The context is not explicitly given, so the response will be general.\n   - **Provide a response**: The answer should acknowledge the user's inquiry into their identity.\n\n4. **Validate Accuracy and Consistency**: The response should be consistent with the general understanding of the question. Since the user has not provided specific details about their identity, the response should be broad and open-ended.\n\n5. **Summarize the Final Result**: The user is asking \"who am I?\" which is an inquiry into their own identity. The answer is that the user is the individual who is asking the question. Without more specific information, a detailed description of their identity cannot be provided.\n\nSo, the final summary would be:\n\nThe user is asking the question \"who am I?\" to seek an understanding of their own identity.

Here are the key facts:\nScientific Name: Ananas comosus\nPhysical Description: It has a tough, spiky, diamond-patterned outer skin (rind) that is usually green, yellow, or brownish. Inside, the juicy yellow flesh surrounds a fibrous core.\nGrowth: Unlike most fruits, pineapples do not grow on trees. They grow from a central stem as a composite fruit, meaning they are formed from many individual berries that fuse together around the core. They grow on a short, leafy plant close to the ground.\nUses: Pineapples are eaten fresh, cooked, grilled, juiced, or canned. They are a popular ingredient in desserts, fruit salads, savory dishes (like pizzas or ham glazes), smoothies, and cocktails.\nNutrition: They are a good source of Vitamin C, manganese, and contain an enzyme called bromelain, which aids in digestion and can tenderize meat.\nSymbolism: The pineapple is a traditional symbol of hospitality and welcome in many cultures.\nAre you asking about the fruit itself, or its use in a specific context?",
