+# 🚀 feat: Complete REST API endpoints for proof management
+
+## 📝 Description
+
+This pull request implements comprehensive REST API endpoints for proof creation, verification, and management with proper error handling and security measures as specified in issue #3.
+
+## ✨ Features Implemented
+
+### Core Functionality
+- ✅ **Proof Creation Endpoint** - Create new cryptographic proofs with full validation
+- ✅ **Proof Verification Endpoint** - Verify proofs using hash and/or Stellar blockchain verification  
+- ✅ **User Proof Management** - Query, filter, and paginate user proofs
+- ✅ **Batch Proof Operations** - Perform bulk operations (verify, delete, update) on multiple proofs
+- ✅ **Rate Limiting and Security** - Multi-tier rate limiting and input validation
+- ✅ **API Documentation** - Comprehensive documentation with examples
+- ✅ **Error Handling** - Comprehensive error handling with proper HTTP status codes
+
+### Security Features
+- Multi-tier rate limiting (general, creation, verification, batch operations)
+- Input validation using express-validator
+- Hash integrity verification
+- Expiration date handling
+- Stellar address format validation
+- UUID validation for user and proof IDs

+
+## 🎯 Acceptance Criteria Met
+
+### ✅ GIVEN proof creation request, WHEN received, THEN creates and stores proof
+- Implemented with full validation
+- Hash integrity verification
+- Proper error handling
+- Returns created proof with metadata
+
+### ✅ GIVEN verification request, WHEN made, THEN returns proof validity
+- Multiple verification methods (hash, Stellar, both)
+- Updates proof status accordingly
+- Handles expired proofs
+- Returns verification results
+
+### ✅ GIVEN user query, WHEN requested, THEN returns user's proofs
+- Filtering by user ID and other criteria
+- Pagination support
+- Sorting options
+- Performance optimized
+
+### ✅ GIVEN batch request, WHEN processed, THEN handles multiple operations
+- Supports verify, delete, update operations
+- Returns detailed success/failure results
+- Proper error handling for individual items
+
+### ✅ GIVEN rate limit, WHEN exceeded, THEN returns proper error response
+- Multi-tier rate limiting implemented
+- Clear error messages with retry information
+- Different limits for different operation types
+
+## 🔧 API Endpoints
+
+### Proof Management
+- `POST /api/proofs` - Create new proof (rate limited: 10/min)
+- `GET /api/proofs/:id` - Get specific proof
+- `PUT /api/proofs/:id` - Update proof
+- `DELETE /api/proofs/:id` - Delete proof
+- `POST /api/proofs/:id/verify` - Verify proof (rate limited: 30/min)
+
+### Query & Operations
+- `GET /api/proofs` - Get user proofs with filtering/pagination
+- `POST /api/proofs/batch` - Batch operations (rate limited: 5/5min)
+- `GET /api/proofs/stats` - Get proof statistics
+
+## 🛡️ Security Implementation
+
+### Rate Limiting
+- **General API**: 100 requests/15 minutes
+- **Proof Creation**: 10 requests/minute
+- **Proof Verification**: 30 requests/minute
+- **Batch Operations**: 5 requests/5 minutes
+
+### Input Validation
+- Stellar address format validation (56 characters, starts with 'G')
+- UUID validation for user and proof IDs
+- Hash format validation (64-128 hex characters)
+- Date validation for expiration dates
+- JSON schema validation for request bodies
+
+## 🧪 Testing
+
+### Test Coverage
+- ✅ All endpoint functionality
+- ✅ Input validation
+- ✅ Error handling
+- ✅ Rate limiting
+- ✅ Pagination and filtering
+- ✅ Batch operations
+- ✅ Security validation
+
+### Running Tests
+```bash
+cd backend
+npm install
+npm test
+```
+
+## 📚 Documentation
+
+- **Complete API Documentation**: `docs/API_DOCUMENTATION.md`
+- **Implementation Overview**: `PROOF_API_IMPLEMENTATION.md`
+- **Request/Response Examples**: Included in documentation
