+# X402 Monetization Demo
+
+A comprehensive Astro demo application showcasing the complete Pinata X402 Monetization API functionality with file upload, management, and payment instruction workflows.
+
+## Features
+
+### File Management
+- Upload files to IPFS via Pinata
+- View uploaded files with metadata (CID, size, type, creation date)
+- Delete files from Pinata
+- Direct links to view files via IPFS gateway
+
+### Payment Instructions
+- Create payment instructions with multiple payment requirements
+- USDC payments on Base and Base Sepolia networks
+- View and manage existing payment instructions
+- Update and delete payment instructions
+
+### CID-Payment Association
+- Associate uploaded file CIDs with payment instructions
+- Attach multiple CIDs to a single payment instruction
+- Each CID can only have one payment instruction at a time
+- View and remove CID associations
+
+### Auto-Run Demo
+- **🚀 One-click complete workflow demonstration**
+- Automatically generates unique timestamped test files
+- Uploads files and creates payment instructions
+- Associates CIDs with payment instructions
+- Provides detailed step-by-step results
+- Perfect for testing and demonstrating the entire API flow
+
+## Setup
+
+1. Copy `.env.example` to `.env` and add your Pinata JWT:
+   ```bash
+   cp .env.example .env
+   ```
+
+2. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+3. Start the development server:
+   ```bash

+
+## Usage
+
+### Quick Start - Auto-Run Demo
+1. **🚀 Click "Run Complete Demo"** - This will automatically execute the entire workflow:
+   - Generate a unique test file with timestamp
+   - Upload it to IPFS
+   - Create a payment instruction with USDC on Base Sepolia
+   - Associate the CID with the payment instruction
+   - Display detailed results
+
+### Manual Workflow
+1. **Upload Files**: Use the file upload form to upload content to IPFS and get CIDs.
+
+2. **Create Payment Instructions**: Fill out the form with payment details:
+   - **Asset**: Contract address (e.g., `0x036CbD53842c5426634e7929541eC2318f3dCF7e`)
+   - **Pay To Address**: Recipient wallet address
+   - **Network**: `base`, `base-sepolia`, `eip155:8453`, or `eip155:84532`
+   - **Amount**: Amount in smallest unit (e.g., `1000000` for token amounts)
+
+3. **Associate Files with Payments**: Click "Attach Payment" on any file to associate it with existing payment instructions.
+
+4. **View and Manage**: 
+   - View all files with their metadata and gateway links
+   - View payment instructions with their requirements
+   - Manage CID associations through modals
+
+5. **Delete and Clean Up**: Remove files, payment instructions, or associations as needed.
