## 📦 Installation

```bash
pip install carver-feeds-sdk
```

## 🚀 Quick Start

### 1. Configuration

Create a `.env` file in your project directory:

```bash
# Required: Carver API Key
CARVER_API_KEY=your_api_key_here
CARVER_BASE_URL=https://app.carveragents.ai  # optional
```

### 2. Basic Usage

```python

from dotenv import load_dotenv
from carver_feeds import get_client

load_dotenv()

# Initialize client from environment variables
client = get_client()

# Fetch topics
topics = client.list_topics()
print(f"Found {len(topics)} topics")

# Fetch entries for a specific topic
entries = client.get_topic_entries(topic_id="topic-123")
print(f"Found {len(entries)} entries")
```

### 3. Using DataFrames

```python
from dotenv import load_dotenv
from carver_feeds import create_data_manager

load_dotenv()

# Create data manager
dm = create_data_manager()

# Get topics as DataFrame
topics_df = dm.get_topics_df()
print(topics_df[['id', 'name', 'is_active']].head())

# Get entries for a specific topic (without content)
entries_df = dm.get_topic_entries_df(topic_id="topic-123")
print(f"Found {len(entries_df)} entries")

# Get entries with content
entries_with_content = dm.get_topic_entries_df(topic_id="topic-123", fetch_content=True)
print(f"Fetched content for {len(entries_with_content)} entries")
```

### 4. Advanced Querying

```python
from dotenv import load_dotenv
from carver_feeds import create_query_engine
from datetime import datetime

load_dotenv()

# Create query engine
qe = create_query_engine()

# Build complex query with method chaining
results = qe \
    .filter_by_topic(topic_name="Abu Dhabi") \
    .filter_by_date(start_date=datetime(2024, 1, 1)) \
    .search_entries("regulation") \
    .to_dataframe()

print(f"Found {len(results)} matching entries")

# Export results
qe.to_csv("results.csv")
qe.to_json("results.json")
```

## 🏗️ Core Components

### API Client (`CarverFeedsAPIClient`)

Low-level API client with comprehensive error handling:

- X-API-Key authentication
- Exponential backoff retry logic for rate limits
- Support for topics and topic-based entry retrieval

### Data Manager (`FeedsDataManager`)

Converts API responses to pandas DataFrames:

- JSON to DataFrame conversion with schema validation
- Hierarchical data views (topic → entry)
- Handles topics and entries
- Content fetching capability

### Query Engine (`EntryQueryEngine`)

High-level query interface with fluent API:

- Method chaining for complex queries
- Filter by topic, date range, and status
- Keyword search with AND/OR logic across multiple fields
- Multiple export formats (DataFrame, CSV, JSON, dict)
- Lazy loading with automatic endpoint optimization

## 📊 Data Model

The SDK works with two main entities in a hierarchical structure:

```
Topic (regulatory bodies like SEC, SEBI, RBI, etc.)
  ↓ 1:N
Entry (individual articles/entries)
```

**Key Fields**:
- **Topic**: `id`, `name`, `description`, `is_active`, timestamps
- **Entry**: `id`, `title`, `link`, `entry_content_markdown`, `description`, `published_at`, `feed_id`, `topic_id`, `content_status`, `s3_content_md_path`, `s3_content_html_path`, `is_active`, timestamps

## ⚡ Advanced Features

### Keyword Search

```python
# Single keyword (case-insensitive by default, searches in title/description)
qe.filter_by_topic(topic_name="Abu Dhabi") \
    .search_entries("regulation", search_fields=['entry_title', 'entry_description']) \
    .to_dataframe()

# Multiple keywords with OR logic (matches ANY)
qe.filter_by_topic(topic_name="Abu Dhabi") \
    .search_entries(["regulation", "compliance", "enforcement"], match_all=False,
                   search_fields=['entry_title', 'entry_description'])

# Multiple keywords with AND logic (matches ALL)
qe.filter_by_topic(topic_name="Abu Dhabi") \
    .search_entries(["financial", "regulation"], match_all=True,
                   search_fields=['entry_title', 'entry_description'])

# Search in full content (requires fetch_content)
qe.filter_by_topic(topic_name="Abu Dhabi") \
    .fetch_content() \
    .search_entries("regulation")  # Searches in entry_content_markdown

# Case-sensitive search
qe.filter_by_topic(topic_name="Abu Dhabi") \
    .search_entries("SEC", case_sensitive=True, search_fields=['entry_title'])
```

**Available Search Fields**:
- `entry_content_markdown` (default, full article content - requires `fetch_content=True`)
- `entry_title` (headline)
- `entry_description` (brief summary)
- `entry_link` (URL)

### Hierarchical Views

Build denormalized DataFrames combining topic and entry data:

```python
from carver_feeds import create_data_manager

dm = create_data_manager()

# Topic metadata only (fast, no entries)
topic_only = dm.get_hierarchical_view(topic_id="topic-123", include_entries=False)

# Full hierarchy for a topic (topic + entries)
topic_data = dm.get_hierarchical_view(topic_id="topic-123", include_entries=True)

# With content fetching
topic_with_content = dm.get_hierarchical_view(
    topic_id="topic-123",
    include_entries=True,
    fetch_content=True
)
```

## 📈 Performance Optimization

### 1. Filter Before Loading

The query engine automatically uses optimized endpoints when you filter before loading data:

```python
# Optimal: Query engine uses get_topic_entries() endpoint
qe = create_query_engine()
results = qe.filter_by_topic(topic_name="Abu Dhabi").to_dataframe()

# Required pattern: Always start with filter_by_topic()
results = qe.filter_by_topic(topic_name="Abu Dhabi") \
    .filter_by_date(start_date=datetime(2024, 1, 1)) \
    .to_dataframe()
```

### 2. Chain Filters Efficiently

Apply filters in order of specificity (narrowest first):

```python
# Good: Narrow by topic first, then apply other filters
results = qe \
    .filter_by_topic(topic_name="Abu Dhabi") \
    .filter_by_date(start_date=datetime(2024, 1, 1)) \
    .search_entries("regulation") \
    .to_dataframe()
```

### 3. Reuse Query Engine

Data is cached after the first load:

```python
qe = create_query_engine()

# First query: loads data from API (~30-60 seconds for all entries)
results1 = qe.filter_by_topic(topic_name="Abu Dhabi").to_dataframe()

# Subsequent queries: use cached data (instant)
results2 = qe.chain().filter_by_topic(topic_name="Healthcare").to_dataframe()
```

### 4. Use Data Manager for Simple Queries

For simple filtering without complex logic, use the Data Manager directly:

```python
# Faster for simple use cases
dm = create_data_manager()
entries = dm.get_topic_entries_df(topic_id='topic-123')  # Direct endpoint call
```

## ⚠️ Error Handling

The SDK provides specific exception types for different error scenarios:

```python
from carver_feeds import get_client, CarverAPIError, AuthenticationError, RateLimitError

try:
    client = get_client()
    topics = client.list_topics()
except AuthenticationError:
    print("Invalid API key. Check your .env file.")
except RateLimitError:
    print("Rate limit exceeded. Please wait before retrying.")
except CarverAPIError as e:
    print(f"API error: {e}")
```

## ✅ Best Practices

1. **Use factory functions** for automatic environment configuration:
   ```python
   from carver_feeds import get_client, create_data_manager, create_query_engine

   client = get_client()  # Automatically loads from .env
   dm = create_data_manager()
   qe = create_query_engine()
   ```

2. **Choose the right component** for your use case:
   - **API Client**: Raw API responses, specific control over requests
   - **Data Manager**: Simple DataFrame operations without complex filtering
   - **Query Engine**: Complex queries with multiple filters and chaining

3. **Handle errors gracefully**:
   ```python
   from carver_feeds import create_query_engine, CarverAPIError

   try:
       qe = create_query_engine()
       results = qe.filter_by_topic(topic_name="Abu Dhabi").to_dataframe()

       if len(results) == 0:
           print("No results found. Try broadening search criteria.")
   except CarverAPIError as e:
       print(f"API error: {e}")
   ```

4. **Export large result sets** to CSV for external processing:
   ```python
   # For large datasets, export rather than keeping in memory
   results = qe.filter_by_topic(topic_name="Abu Dhabi")
   results.to_csv("abu_dhabi_entries.csv")  # Saves ~50-100 MB to disk
   ```
