+# Financial Agent (Python)
+
+A Python implementation of the FinGuide financial education agent using FastAPI, OpenAI, and Nevermined Payments.
+
+## Features
+
+- **Two Agent Versions**:
+  - `index_unprotected.py` - Free access financial education agent
+  - `index_nevermined.py` - Protected agent with Nevermined payment integration
+
+- **Dynamic Credit System** (Protected version only):
+  - Credits charged based on actual token usage
+  - Formula: `10 * (actual_tokens / max_tokens)`, minimum 1 credit
+  - Rewards concise responses with lower costs
+
+- **Session Management**: Maintains conversation context across multiple questions
+- **Loading Animation**: Visual feedback during API calls
+- **Educational Focus**: Provides financial education rather than investment advice
+
+## Setup
+
+1. **Install dependencies**:
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+2. **Environment Configuration**:
+   ```bash
+   cp .env.example .env
+   # Edit .env with your API keys and configuration
+   ```
+
+3. **Required Environment Variables**:
+   ```
+   OPENAI_API_KEY=your_openai_api_key_here
+
+   # For protected agent only:
+   BUILDER_NVM_API_KEY=your_builder_api_key_here
+   SUBSCRIBER_NVM_API_KEY=your_subscriber_api_key_here
+   NVM_ENVIRONMENT=staging_sandbox
+   NVM_AGENT_ID=your_agent_did_here
+   NVM_PLAN_ID=your_plan_did_here
+   ```
+
+## Running the Agent
+
+### Unprotected Agent (Free Access)
+```bash
+cd agent
+python index_unprotected.py
+# Server starts on http://localhost:8001
+```
+
+### Protected Agent (Nevermined Integration)
+```bash
+cd agent
+python index_nevermined.py
+# Server starts on http://localhost:8000
+```
+
+## Running the Client
+
+### Test Unprotected Agent
+```bash
+cd client
+python index_unprotected.py
+```
+
+### Test Protected Agent
+```bash
+cd client
+python index_nevermined.py
+```
+
+## API Endpoints
+
+### POST /ask
+Send a financial question to FinGuide.
+
+**Request Body**:
+```json
+{
+  "input_query": "What is diversification?",
+  "sessionId": "optional-session-id"
+}
+```
+
+**Response** (Unprotected):
+```json
+{
+  "output": "Diversification is like not putting all your eggs in one basket...",
+  "sessionId": "generated-or-provided-session-id"
+}
+```
+
+**Response** (Protected):
+```json
+{
+  "output": "Diversification is like not putting all your eggs in one basket...",
+  "sessionId": "generated-or-provided-session-id",
+  "redemptionResult": {
+    "creditsRedeemed": 3,
+    "error": null
+  }
+}
+```
+
+### GET /health
+Health check endpoint.
+
+**Response**:
+```json
+{
+  "status": "ok"
+}
+```
+
+## Architecture
+
+- **FastAPI**: Modern Python web framework with automatic OpenAPI docs
+- **OpenAI**: GPT-4o-mini for natural language responses
+- **Nevermined Payments**: Payment and observability integration (protected version)
+- **Session Management**: In-memory conversation history
+- **Async/Await**: Non-blocking request handling
+
+## Key Differences from TypeScript Version
+
+1. **FastAPI** instead of Express.js
+2. **Pydantic models** for request/response validation
+3. **Async/await** pattern throughout
+4. **Python-style** naming conventions (snake_case)
+5. **Local payments-py** library integration
+
+## Development
+
+The Python implementation maintains feature parity with the TypeScript version while following Python best practices and idioms.
