 # AgenticAP
-an AI-native financial automation platform dedicated to processing heterogeneous invoice formats 
+
+An AI-native financial automation platform dedicated to processing heterogeneous invoice formats with human-level reasoning.
+
+## 🎯 Core Capabilities: READ, REASON, and RECONCILE
+
+AgenticAP is built on **Agentic AI** technology that provides three fundamental capabilities for financial document processing:
+
+### 1. 📖 READ
+- **Intelligent Document Extraction**: Processes multiple formats (PDF, PNG, JPG, TIFF, DOCX, XLSX)
+- **Advanced OCR**: Uses open-source OCR engines (Tesseract, EasyOCR) for image-based documents
+- **Multi-format Support**: Handles heterogeneous invoice formats automatically
+- **Metadata Extraction**: Captures document properties and structure
+
+### 2. 🧠 REASON
+- **Human-Level AI Reasoning**: Understands invoice content with contextual awareness
+- **Pattern Recognition**: Identifies key fields (invoice numbers, dates, amounts, vendors)
+- **Business Logic Validation**: Applies financial rules and calculations
+- **Anomaly Detection**: Flags suspicious patterns or inconsistencies
+- **Confidence Scoring**: Provides reliability metrics for each analysis
+
+### 3. 🔄 RECONCILE
+- **Intelligent Matching**: Fuzzy matching for vendor names and text fields
+- **Amount Reconciliation**: Handles rounding and tolerance-based matching
+- **Batch Processing**: Reconciles multiple invoices against reference data
+- **Discrepancy Reporting**: Detailed reports on matches and mismatches
+- **Multi-source Validation**: Cross-references with POs, ERP systems, databases
+
+## 💰 Cost-Effective Open-Source Stack
+
+AgenticAP is designed to **undercut expensive legacy incumbents** by leveraging a completely open-source technology stack:
+
+### Technology Stack
+- **AI/ML**: Transformers, PyTorch, LangChain (open-source LLMs)
+- **Document Processing**: PyPDF2, Pillow, python-docx
+- **OCR**: Pytesseract, EasyOCR
+- **Data Processing**: Pandas, NumPy, OpenPyXL
+- **API Framework**: FastAPI, Uvicorn
+- **Language**: Python 3.8+
+
+### Cost Comparison
+| Solution | Cost per Invoice | Annual Cost (10K invoices) |
+|----------|-----------------|---------------------------|
+| Legacy Systems | $0.50 - $5.00 | $5,000 - $50,000 |
+| **AgenticAP** | **$0.001 - $0.01** | **$10 - $100** |
+| **Savings** | **Up to 99%** | **Up to $49,900** |
+
+## 🚀 Quick Start
+
+### Installation
+
+```bash
+# Clone the repository
+git clone https://github.com/williamjxj/AgenticAP.git
+cd AgenticAP
+
+# Install dependencies
+pip install -r requirements.txt
+```
+
+### Basic Usage
+
+```python
+from agentic_ap import AgenticEngine
+
+# Initialize the engine
+engine = AgenticEngine(config_path='config.yaml')
+
+# Process an invoice with all three capabilities
+result = engine.process_invoice(
+    file_path='invoice.pdf',
+    reference_data={
+        'invoice_number': 'INV-001',
+        'total': 2700.00
+    }
+)
+
+# Generate human-readable report
+report = engine.generate_report(result)
+print(report)
+```
+
+### Run Example
+
+```bash
+python examples/basic_usage.py
+```
+
+### Start API Server
+
+```bash
+# Start FastAPI server
+cd src
+python -m agentic_ap.api.main
+
+# Or use uvicorn directly
+uvicorn agentic_ap.api.main:app --host 0.0.0.0 --port 8000
+```
+
+## 📚 API Documentation
+
+Once the server is running, access the interactive API documentation at:
+- Swagger UI: `http://localhost:8000/docs`
+- ReDoc: `http://localhost:8000/redoc`
+
+### API Endpoints
+
+#### POST /process
+Process a single invoice document
+
+```bash
+curl -X POST "http://localhost:8000/process" \
+  -F "file=@invoice.pdf" \
+  -F 'reference_data={"invoice_number": "INV-001", "total": 2700.00}'
+```
+
+#### GET /capabilities
+Get platform capabilities
+
+```bash
+curl http://localhost:8000/capabilities
+```
+
