### Step 1: Setting Up the Environment

**1.1 Create a Virtual Environment:**

```bash
python -m venv .venv
source .venv/bin/activate
```

**1.2 Install Dependencies:** Create and populate `[requirements.txt]` with:

```text
openai
gradio
python-dotenv
requests
pytube
```

Then install them:

```bash
pip install -r requirements.txt
```

**1.3 Environment Variables:** Create a `.env` file with your API keys:

```text
AIML_API_KEY=your_api_key
GOOGLE_MAPS_API_KEY=your_google_maps_api_key
```

> Here's a brief tutorial: [How to get API Key from AI/ML API. Quick step-by-step tutorial with screenshots for better understanding](https://medium.com/@abdibrokhim/how-to-get-api-key-from-ai-ml-api-225a69d0bb25).

**1.4 Git Ignore:** Add `.gitignore`:

```text
.env
.venv
__pycache__
*.pyc
.DS_Store
```

---

### Step 2: Project Structure

Your final project directory should look like:

```bash
Bagoodex_Web_Search/
├── .env
├── .gitignore
├── requirements.txt
├── app.py
├── bagoodex_client.py
├── helpers.py
├── prompts.py
└── r_types.py
```

### Step 3: Key Files Explained

#### 3.1 `[bagoodex_client.py]`

- Implements API interactions with `bagoodex` and GPT services.

- Import necessary modules:
```py
import os
import requests
from openai import OpenAI
from dotenv import load_dotenv
from r_types import ChatMessage
from prompts import SYSTEM_PROMPT_BASE, SYSTEM_PROMPT_MAP
from typing import List
```

- Load environment variables and set up the API client:


```py
load_dotenv()
API_KEY = os.getenv("AIML_API_KEY")
API_URL = "https://api.aimlapi.com"
```

- Define the `BagoodexClient` class:

```py
class BagoodexClient:
    def __init__(self, api_key=API_KEY, api_url=API_URL):
        self.api_key = api_key
        self.api_url = api_url
        self.client = OpenAI(base_url=self.api_url, api_key=self.api_key)
```

- Includes methods:
  - `complete_chat()`: Handles general chat interactions.
  
  ```py
  def complete_chat(self, query):
        """
        Calls the standard chat completion endpoint using the provided query.
        Returns the generated followup ID and the text response.
        """
        response = self.client.chat.completions.create(
            model="bagoodex/bagoodex-search-v1",
            messages=[
                ChatMessage(role="user", content=SYSTEM_PROMPT_BASE), 
                ChatMessage(role="user", content=query)
            ],
        )
        followup_id = response.id  # the unique ID for follow-up searches
        answer = response.choices[0].message.content
        return followup_id, answer
  ```
  - `base_qna()`: Handles basic Q&A interactions. Basically we'll use this for follow-up questions. It's pretty reusable. We should pass the different system prompts based on our use case.
  ```py
    def base_qna(self, messages: List[ChatMessage], system_prompt=SYSTEM_PROMPT_BASE):
        response = self.client.chat.completions.create(
            model="gpt-4o",
            messages=[
                ChatMessage(role="user", content=system_prompt), 
                *messages
            ],
        )
        return response.choices[0].message.content
  ```

  - Retrieves IDs for fetching follow-up resources (links, images, videos, maps).
  ```py
    def get_links(self, followup_id):
        headers = {"Authorization": f"Bearer {self.api_key}"}
        params = {"followup_id": followup_id}
        response = requests.get(
            f"{self.api_url}/v1/bagoodex/links", headers=headers, params=params
        )
        return response.json()

    def get_images(self, followup_id):
        headers = {"Authorization": f"Bearer {self.api_key}"}
        params = {"followup_id": followup_id}
        response = requests.get(
            f"{self.api_url}/v1/bagoodex/images", headers=headers, params=params
        )
        return response.json()

    def get_videos(self, followup_id):
        headers = {"Authorization": f"Bearer {self.api_key}"}
        params = {"followup_id": followup_id}
        response = requests.get(
            f"{self.api_url}/v1/bagoodex/videos", headers=headers, params=params
        )
        return response.json()

    def get_local_map(self, followup_id):
        headers = {"Authorization": f"Bearer {self.api_key}"}
        params = {"followup_id": followup_id}
        response = requests.get(
            f"{self.api_url}/v1/bagoodex/local-map", headers=headers, params=params
        )
        return response.json()

    def get_knowledge(self, followup_id):
        headers = {"Authorization": f"Bearer {self.api_key}"}
        params = {"followup_id": followup_id}
        response = requests.get(
            f"{self.api_url}/v1/bagoodex/knowledge", headers=headers, params=params
        )
        return response.json()
  ```

  Note: First, you must first call the standard chat completion endpoint `complete_chat()` with your query. The chat completion endpoint returns an ID, which must then be passed as the sole input parameter `followup_id` to the `bagoodex/links`, `bagoodex/images`, `bagoodex/videos`, `bagoodex/local-map` and `bagoodex/knowledge` endpoints.

#### 3.2 `[app.py]`

- Import necessary modules:
```py
import os
import gradio as gr
from bagoodex_client import BagoodexClient
from r_types import ChatMessage
from prompts import (
    SYSTEM_PROMPT_FOLLOWUP, 
    SYSTEM_PROMPT_MAP, 
    SYSTEM_PROMPT_BASE, 
    SYSTEM_PROMPT_KNOWLEDGE_BASE
)
from helpers import (
    embed_video,
    format_links,
    embed_google_map,
    format_knowledge,
    format_followup_questions
)
```

- Initialize the `BagoodexClient`:

```py
client = BagoodexClient()
```

- Central application logic.
```py
# ----------------------------
# Chat & Follow-up Functions
# ----------------------------
def chat_function(message, history, followup_state, chat_history_state):
    """
    Process a new user message.
    Appends the message and response to the conversation,
    and retrieves follow-up questions.
    """
    # complete_chat returns a new followup id and answer
    followup_id_new, answer = client.complete_chat(message)
    # Update conversation history (if history is None, use an empty list)
    if history is None:
        history = []
    updated_history = history + [ChatMessage({"role": "user", "content": message}),
                                ChatMessage({"role": "assistant", "content": answer})]
    # Retrieve follow-up questions using the updated conversation
    followup_questions_raw = client.base_qna(
        messages=updated_history, system_prompt=SYSTEM_PROMPT_FOLLOWUP
    )
    # Format them using the helper
    followup_md = format_followup_questions(followup_questions_raw)
    return answer, followup_id_new, updated_history, followup_md

def handle_followup_click(question, followup_state, chat_history_state):
    """
    When a follow-up question is clicked, send it as a new message.
    """
    if not question:
        return chat_history_state, followup_state, ""
    # Process the follow-up question via complete_chat
    followup_id_new, answer = client.complete_chat(question)
    updated_history = chat_history_state + [ChatMessage({"role": "user", "content": question}),
                                            ChatMessage({"role": "assistant", "content": answer})]
    # Get new follow-up questions
    followup_questions_raw = client.base_qna(
        messages=updated_history, system_prompt=SYSTEM_PROMPT_FOLLOWUP
    )
    followup_md = format_followup_questions(followup_questions_raw)
    return updated_history, followup_id_new, followup_md
```

- Next setup `Local map` and `Knowledge base` functions.
```py
def handle_local_map_click(followup_state, chat_history_state):
    """
    On local map click, try to get a local map.
    If issues occur, fall back to using the SYSTEM_PROMPT_MAP.
    """
    if not followup_state:
        return chat_history_state
    try:
        result = client.get_local_map(followup_state)

        if result:
            map_url = result.get('link', '')
            # Use helper to produce an embedded map iframe
            html = embed_google_map(map_url)

            # Fall back: use the base_qna call with SYSTEM_PROMPT_MAP
            result = client.base_qna(
                messages=chat_history_state, system_prompt=SYSTEM_PROMPT_MAP
            )
            # Assume result contains a 'link' field
            html = embed_google_map(result.get('link', ''))
        new_message = ChatMessage({"role": "assistant", "content": html})
        return chat_history_state + [new_message]
    except Exception:
        return chat_history_state

def handle_knowledge_click(followup_state, chat_history_state):
    """
    On knowledge base click, fetch and format knowledge content.
    """
    if not followup_state:
        return chat_history_state

    try:
        print('trying to get knowledge')
        result = client.get_knowledge(followup_state)
        knowledge_md = format_knowledge(result)

        if knowledge_md == 0000:
            print('falling back to base_qna')
            # Fall back: use the base_qna call with SYSTEM_PROMPT_KNOWLEDGE_BASE
            result = client.base_qna(
                messages=chat_history_state, system_prompt=SYSTEM_PROMPT_KNOWLEDGE_BASE
            )
            knowledge_md = format_knowledge(result)
        new_message = ChatMessage({"role": "assistant", "content": knowledge_md})
        return chat_history_state + [new_message]
    except Exception:
        return chat_history_state
```

- Advanced search functions.
```py
# ----------------------------
# Advanced Search Functions
# ----------------------------
def perform_image_search(followup_state):
    if not followup_state:
        return []
    result = client.get_images(followup_state)
    # For images we simply return a list of original URLs
    return [item.get("original", "") for item in result]

def perform_video_search(followup_state):
    if not followup_state:
        return "<p>No followup ID available.</p>"
    result = client.get_videos(followup_state)
    # Use the helper to produce the embed iframes (supports multiple videos)
    return embed_video(result)

def perform_links_search(followup_state):
    if not followup_state:
        return gr.Markdown("No followup ID available.")
    result = client.get_links(followup_state)
    return format_links(result)
```

- Uses `Gradio` for UI. Settign up CSS.
```py
# ----------------------------
# UI Build
# ----------------------------
css = """
#chatbot {
    height: 100%;
}
h1, h2, h3, h4, h5, h6 {
    text-align: center;
    display: block;
}
"""
```

- Handles chat, follow-up interactions, and advanced search features (images, videos, links).
